Hi there, I kinda need some help here My phone memory just gets filled up more and more with no real reason every day. I have installed only 5-6 very important programs on the internal memory, but it still is almost filled up, although I have no pictures, music or videos in the phone.
Is there any way I can find which files are taking the most space and remove them, if possible? Or which programs are installed on the internal memory and how much space do they take?
Unfortunately, I can't do this while the phone is connected with my pc - it has some strange problem with analyzing size of a folder with folders inside it. For example, the Windows folder is calculated 0 bytes, but if I open it, every folder inside of it would have some size (except if it has another list of folders inside itself) :|
I really hope you can help me
You are not the first to post on this. Have you tried searching the forums on here to find an answer to your problem?
In no particular order the reasons for your problem are:
-Open applications not being closed.
- Caches running in device memory rather than on the SD card
- Music, video, pictures taking up space if not installed to external memory card.
- All applications being installed to internal memory.

1st, thanks for posting But:
I close all my apps all the time with the Task Manager.
As I said, I have no songs, pictures or any other type of multimedia saved on the internal memory.
I've got only 6-7 most important apps installed on the internal memory (and after installing them the memory wasn't even half full).
And please explain to me how can I use the camera tool for searching for solutions

What that important software is? Maybe one of them is storing it's temp files and cache files in phone memory and does not delete them when you close the app it self?
Triteata,
My apologies, wrong link. Never answer a post when you are tired . This is what I wanted to post: http://www.google.com/advanced_search?q=+site:http://forum.xda-developers.com&hl=en&lr=&as_qdr=all
Do take a look in the hints and tips thread which will tell you how to move your album and web browser caches to your SD card and help to shed some solutions on your problem.
WB
PS: Name the apps which are open please. These may be enough to kill your memory. The fact that they are "important" to you is irrelevant to how much memory they may be using up in cache use, etc.
Well:
Core Player
Duttys Task Manager
SPB Backup
Skype
Pocket RAR
Finger Keyboard
BsB Tweaks
Meon Game (downloaded via Marketplace :| )
Shazam
RegEditor
Total Commander
Although they're plenty, I doubt that any of them makes a serious Cache folder (except for Skype may be ).
Anyway, after deleting all the cache from albums, google maps and opera and moving it to the Card, I now have 60 mb of free space
Thanks for helping!
Actually, there is NO reason to install any of these programs in internal memory. It may help to uninstall and put them all on the SD Card.

I went to take a picture today with my 8125 and it said i only had 22 remaining.... i swear a few days ago it was well over 50. Im assuming the pictures get saved to the "storage" memory by default so i checked my memory and it says i only have 6.5 mb left. I have no clue how this is possible since i dont even have a lot of programs installed. here is what i have installed 3rd party:
tonaya weather to go
magic button
agile messenger
TCPMP with two plugins
TomTom w/ one voice
Not sure what this one is but : FdcSoft PPCContacts manager. (let mek now if i can delete this one)
along with that i have 13 full res pictures and the stock ones it came with. Im running aku2.3 if that has any affect...
like i said i just dont understand how i am using almost 40mb out of 47. and im not quite sure what program memory consists of but that is almost have full at around 22mb of 44mb. Thanks for the help

DO not assume anything. Usually by default, items are stored to your Main Memory. Go in and check all your programs, change the default "save to" and clear cache and temp files.

I can't say I understand...could you please explain a little more please. do all of the new programs I install go to storage memory or program? I'm just confsed on what to clear out
well i posted this topic earlier today and i said that i had around 6mb of free storage space. I just went to install opera and it said my storage space was down to 2mb! I havnt installed anything or taken any pictures since i started this topic and i lost 4mb of storage already. How is this happening?? I did 2 soft resets and my storage memory never went up. Im really confused as to how this thing is eating my storage memory without me doing anything. I had to delete agile messenger just to gain some space! Please help with this
Storage mem is where you install apps and where apps by default save their files (pictures, video's, temp files, IE cache, Word documents etc). When you use your cam to take pictures, they come in the mydocuments folder on your storage mem. To change this, you have to go into the options of all apps you use and change the default storage location for the files to SD card. For instance: in the camera app, go to the settings, options, general and change the location to storage card.
With file explorer you can search your device for these files, perhaps your pics are taking up so much space? You can also use the built-in search function in start-programs and search for files larger than 64 kb, that should show you the culprits.
Program Mem under WM5 is only used to run apps, not to store them. It wll gradually fill up since not all apps are properly closed, even with task managers. Soft-resetting will empty your program mem from these apps and free up your RAM.
Storage mem is ROM mem and will not be emptied by a soft reset. There must be a lot of files in your storage mem that take up the place, so find out which apps do that. perhaps you have been surfing and there are large temp files from IE on your device?
Thanks for the advice, that is pretty much the answer i needed. One more question though, where should i regularly look to delete files? I will change my picture save location to my stroage card but what are some places i should always be clearing out? Thanks
Edit: I think i may have found the main culprit....one i forgot i transfered a 6mb song for a ring tone and second i went to windows=profiles=guest=temp internet files and cleared all that out and now im up to 22mb of free storgage! Is there any way i can not have it save the temp files or something? Also, in the windows folder it has all of my sounds/ring tones and those same files are also in the Rings folder. It wont let me delete them out of the windows folder and i dont want to delete them out of the rings folder and have it not work. What should i do?
You can run the search function in start-programs regularly if your storage mem goes down to fast for your liking to see large files that hog your storage mem (like files and frames in your temp folder that you downloaded or some app dumped there).
To clear out the IE cache, start IE, tap menu-options-memory and click the buttons delete history and delete files.
I have no idea which other locations to check, I only applied the camera option and clear out the IE cache once in a while (f I remember to). I have lots of apps installed in storage mem and still approx 15 MB free, so freeing up space has never been an issue for me.
good luck with it!
PS judging on your installed apps, I have no idea what can hog your storage so extremely. Perhaps the weather app is saving all downloaded data somewhere on main? I presume that your TT maps are on storage card (they are too big for intenal strage anyway)
PPS AFAIK PPCContact Manager helps you to select all your contacts in one go, for batch sending them trough BT to e.g. a BT carkit or other operations you want to carry out involving all contacts instead of one by one. tap and hold on a contact and you should see "Select all contacts" in the pop-up menu.
youve been a huge help koksie, i appreciate it. Any idea why my soungs are stored in the windows folder and under windows/rings? It wont let me delete them out of the windows folder but it will out of the rings folder. The only reason i dont want to delete them out of the rings folder is i feel if i do then i wont be able to select the deleted ones as ring tones even though they are still in my windows folder. Maybe i should just leave this as is...
Have a search for a free utility called Where Is My RAM? WIMR. As I can best recall this will run on WM5 too and will list your files in order of size. A real boon!
There's a program called Registry Wizard made by one of the geniuses here that will set your IE temp/cache files to be saved to the storage card. I use it and love it! It also has a lot of other tweaks for performance, annoyances, etc....
Do a search for it.
Hell....it's still on the first page when I do a search for "8125"

I store all my songs on the storage mini SD card. Only my ringtones and mp3 I want to set as ringtone are in the windows/rings dir. All the songs I only use for listening are on my SD card. Use total Commander (freeware) to delete all the stuff you don't need in the windows dir. This app has more possibilities than the standard file explorer. Just save your songs you need for ringtones on your main mem (windows/rings) and move all other songs to your SD card. Sorry, kinda wasted right now, just got home at 4.30 AM after "some" drinking, so I might not make much sense, but I might be more clear later on after some sleep...
Apologies if its a repeat post but I've been searching and could not find an answer.
How can I increase the memory on my XDA Pro. The memory remaining is showing 0.27 MB and it is constantly coming up with a "Storage Memory is Critically Low" message.
I store most of my work on the SD Card anyway. I've tried looking for large files to delete from the Pro but cant find anything.
Please help.
Thanks a lot everyone.
It sounds to me as if you have used up your storeage memory with applications. Assess your usage priority and move the programs that you don't use a lot of to your memory card.
How would I do that?
Is it just a case of copy and paste?
Also using something like Clear Temp (freeware) http://www.pocketpcfreewares.com/en/index.php?soft=1489 will clear away all of those pesky temp files that take up all of your space.
You'll probably find you regain lots of space by doing this.
Search the forum for UPX - you can comress your apps to free up space and many of them will run faster too

For moving programs, no. The best thing would be to uninstall from main memory and reinstall on a storage card. If there's any data related to an app, you'd want to back that up first so you don't lose it. I have a 4GB card in my Universal and have most of my third party apps installed on it to save the device memory. I just leave it in all the time.
Thank you all.
I finally managed to find out that I had over 10 MB in the temporary internet files, deleted all those and everything seems fine.
Also, managed to find out a lot of useful stuff as mentioned by you all in the above post.
Thank you all once again.
This is all great advice, but how do you tell which apps or data are located in Main memory? Is there some way to tell?
Lee.
I am receiving the current message on my hd2 and would like to know how i can repair the problem as it keeps popping up on the screen all the time
'Storage memory is critically low. If the storage memory is not increased, other programs may not be able to start. Use File Explorer to delete files that are no longer needed or move some files to a storage card'
Any advice please?
Simple advice- you've got too much installed or saved to internal memory rather than the storage card.
Common culprits are browser caches for PIE and Opera, the HTC Album cache, media files like videos, music and pictures etc.
Use File Explorer to look in all the sub folders of My Documents as a starting point. Try moving all the big files over the the storage card.
Download Treeview from Microsoft Marketplace- it's free and can show you where all the storage memory is going.
should i do this through the phone direct or the pc?

You can do either- as long as you connect using ActiveSync rather than Disk Drive mode.
Using the PC is probably a slightly easier experience as Windows Explorer is more informative than the mobile version!

You don't have to do all that. It works great out of the box as well. Those are just possibilities, to customize it and tweak it.
Uninstall everything you have installed on your phone and reinstall it to the storage card. Always install applications to the storage card. That should fix your 'problem'.
Additionally, open the File Explorer, go to \Windows and delete the folder YouTube. That gives you additional free space but the folder comes back when you watch YouTube videos, so you can do this from time to time.
can i drag and drop my applications folder into the storage card via the pc?
Yes, but then the links in the start menu won't work anymore. Think of what happens when you move the Program Files folder on your PC. It's the same here.
can someone give me a step by step guide for doing this task please.
Go to Settings, Manage Applications, Uninstall Applications. There, uninstall all the applications you have installed to teh main memory.
Then reinstall them, this time to the storage card.
And delete the YouTube cache from time to time.
When we're speaking of free storage memory, how much memory do you all have free?
Mine is around 20 mb, is it to small?
Beacuse when i watched a video on youtube i got the same message as in the first post.

As I suggested in the earlier post, this is nothing to do with installed programs- most of those are pretty small and are unlikely to be grabbing the majority of your memory.
It is most likely that you have allowed some large files to be stored in the main memory. By default the phone DOES store most big user files like photos and videos on a storage card, but perhaps that has been altered somewhere?
You need to use a file finding utility to sort this- if Treesize is not available in your locality via Marketplace (or you can't access Marketplace) then you can try Spacefinder, a tiny, free program that will sort your files and folders in order of size, giving a hint as to where the memory may have gone. You can also download Treesize Mobile direct from Jam Software
Stuff like CleanRAM, SKTools etc is OK for clearing RAM but has no effect on Storage Memory apart from clearing some caches, though this can help a lot.
One other tip- as has been suggested, try and install programs onto a storage card, but not if they are system programs like Today plug-ins or keyboards etc. These must go into device memory otherwise you may get some startup errors.
This baffles me. I have just got an HD2 to replace my HD - I started to put exactly the same programs onto the HD2 as I had previously installed on my HD (I install all programs on the device). I got the low memory warning long before I put all the programmes on - on a brand new device with no internet browsing/video/music on device itself.
My HD has more memory than my HD2 - how is that possible?
None of these explanations seem to explain how this happens on my HD2 but not my old HD. I have NEVER had a low memory warning on my HD despite having used it for over a year and having installed more on it than I have managed on the HD2.
I have recently found the pre-installed Google Maps created a cache folder in device memory and pumped it up to 25 Megs. Deleted it of course.

The HD2 has more memory (ROM) but a huge chunk (150MB) is taken up by all the HTC Sense gubbins, leaving a relatively smaller amount free to the user. Ultra light cooked ROMs give about 150MB more ROM, and light ROMs about 100MB more than the default ROM.
It also seems that a lot of caching is going on- Album, Googlemaps, Browsers etc eating up ROM.
I've had my HD2 for about a week now. I've installed maybe 3 or 4 apps directly to the device (not to SD Card). I'm now in the situation of not being able to d/l any videos etc. due to having insufficient memory! I can't believe it!!!
Device total storage stands at 200.40MB
Used storage= 189.02MB
Free storage= 11.38MB
However below this info my phone is showing ''Free program storage'' as being 178.38MB. While my SD card is showing Free Memory being at 1453.95MB.
Would the solution be to transfer everything to SD card and only install to the SD card in future?
Yep I would, saves the phones internal memory
I install any non-system apps to the card, anything that needs access to the system files goes on my phone

Thank you. That's really helpful.
These reports of low memory are really starting to bug me.
It would appear that there is something going on that is not fully understand because there is no way that you should run out of phone storage memory with only 4 apps installed!
A serious in depth investigation is needed to unearth the cause.
I have 27 apps installed and I have 152Mb of storage memory left.
Could you tell us what ROM you are running?
Did you go to the task manager and see what is running and try ending the tasks? If you don't kill programs in there they will eat up your system memory... Specially if you are downloading a bunch of porn... Opera is probably using up a bunch.

Thats not the memory the OP was talking about. Unless I've got it all wrong! Or you have!
I think you are referring to Program memory. The OP was talking about Storage memory and how something was using it up.
This is all very strange.
Things you should definitely look at
1. Where are your camera pictures and camcorder videos stored? ---> if you select device and not storage on the camera app or camcorder app settings, then u are my friend putting pictures and videos you've taken to the sdcard...
solutions: go to ur camera app settings and look at where u are storing the pictures...
or go to ur file explorer, go to ur device's memory and check if they are there...
if they are there, then copy and paste them to ur sd card...
2. set ur outlook, yahoo e-mail and stuff to be stored in sd card, not device's memory...
3. idk what else you have in there to have that very little memory left...
Oh I missed that... My phone has 686.12 Total Storage, 190.64 used, 495.48 free. I have installed all of the apps on the Storage card though. If his says that the total storage is 200 or whatever, that sounds like the problem... Should be like a gb of total device memory between storage and programs...
It seems that Opera 9 saves downloads to a folder on the phones 'device memory', but it doesn't always delete them when you tell opera to do so in the downloads menu tab.
It saves them too: \My Device\Windows\opera9\profile\download
When I deleated most of the files there it released over 110 MB of space in the device storage.
I wonder where other programs save similar files?
Sam.
Have a look here http://forum.xda-developers.com/showthread.php?t=583638 for tips on freeing some space. The HTC Album cache is my biggest storage hog. Even then, like you, I have just a few programs installed to my internal store and hardly any memory left. The UK version has less storage than the USA HD2 which makes matters worse.
maybe for the euro hd2, cleartemp could help. It can help find those caches and delete them regularly.
I have the tmous version and flash all the time so I don't have that problem.
Also look for the youtube cache. I've heard it can get pretty big if you look at a lot of youtube vids.
edit: go find cleartemp. There are loads of stuff it can clear for you.
I found 10mb under thumbs.db alone.
Not to mention a few mb for google maps and for opera cache each.
you can also add custom folders to be cleaned as well. I haven't looked too much into it, but maybe I should.
Just remember that caches help your phone run faster, so don't erase them unless you need the memory.
This thread has good suggestions. But most are usual recommendations that will help but perhaps not resolve the issue completely (well a couple of posts do mention temp issues). I had a similar experience recently.
A couple of facts:
1. I install all my apps into the main memory. Never had issues. Opera, IE cache, temps all there by default.
2. I download and save on SD. Music, films, pictures, documents, Android are all there.
3. Still I have plenty of room for storage.
And then I suddenly had that warning!
The cause was temp made by the default ZIP utility that used up almost all my storage space. That utility works fine until I wanted to uncompress 160 mb zip from SD into another SD folder. It started uncompressing, used all storage temp space, gave me error, and closed. It didn't clean the temp though!
I cleaned a bit manually and then installed SK tools that cleaned my device properly and everything is fine now. It is very simple issue and similar to running out of disk space on a PC.
Bottom line: it is unlikely that usual apps use so much storage. I bet on downloads and big user files left in storage and finally huge temp files as leftovers of unsuccessful uncompressing for example.
Hello everyone,
Have anyone heard about some sort of filesystem extension to the Storage Card? I once read somewhere, that it could fool WiMo, extending the windows folder (maybe other folders too) into the storage card. I tried to google it, but couldn't find anything. Does anyone knows what this is? Or any other technique to extend the internal storage other than the well known tips and installing/moving the apps to storage card?
Thanks much,
Fernando

Hello Angelo, thanks for the quick reply!
Before someone yells at me that every noob should read the stickies and search before posting, let me explain that I'm actually looking for some light on this "filesystem extension" or something similar... I guess I should have written (already edited) and named the thread more carefully, since I'm not really running out of space, just looking for options on extending the internal storage...
As for the stickies, I already have them applied - tip 67 (Save Some Space in Phone Storage Memory), 97 (Save Camera Photos Direct to Storage Card) or latter on the thread (moving the bluetooth inbox, ringtones and opera cache to the SD card), I'm aware of them and already have them applied, but yet if we keep installing every nice piece of software we find interesting, eventually we are going to run out of internal storage, even with several GBs free on storage card, but I know that installing a bunch of stuff it's not the expected or usual behavior.
Thanks again for the prompt and polite reply.
You won't run out of internal storage, delete My Device/Application Data/HTC/HTC ALBUM contents and the files inside 'Cache' as well, you can hold up to 20 meg or more in there.
Another idea is to delete My Device/Windows/Rings and just use your custom ring tone, message tones, if you use a decent file manager i.e. Resco you can uncover the hidden tones and delete them also, saving you around 8 meg or so.
My Device/My Wallpapers will save you another ~4 or so.
After flashing an updated Energy ROM I usually have exactly 38 meg of used storage, and after a few days of cache it usually settles to around 50-55 meg, I clear the HTC Album cache from time to time and it always keeps it well under 60 mbs.
I prefer to keep things on the internal storage (I mean system files, caching etc.) as it just seems faster than keeping it on the SD card, and it will also save you a wee bit of battery life as it won't need to keep accessing the card.

Well then, since You already tweaked all possible items unfortunately this will be the maximum You can get.
Since Nov. 2009 - when I received my HD2 - I carefully read every post concerning int. memory and now with approx. 50 apps installed (all to storage card) I can keep the internal mem filled at 70% (approx. 54MB free mem).
Never forget: emails, sms, mms, contacts etc. are stored internally: the more You keep, the more mem is eaten up.
Since I use only one ringtone and only two avatars (1 x male, 1 x female) for contacts, no animated wallpapers and one selfmade background I deleted all other ringtones, wallpapers and anims.
If Copilot is installed on Your device move it to sd card also (PocketMechanic worked best for me to do this), makes up for another 10 MB of free space.
Enjoy
Thank you both for the reply!
Well, right now I have about 63 megs of free space in the internal storage, but there are still some apps I haven't installed after I flashed this new ROM.
A month ago I was trying almost every app - freewares and sharewares - to sort out what I really need to buy and which free apps work for me, but before I could test half of the apps and games I downloaded, I ran out of space. It wasn't really a problem since I was planning to hard reset my HD2 and then keep only the nice ones, but I decided to search for a possible solution and then read somewhere about this "filesystem extension"... But seems that I misplaced the bookmark and never found anything else on this... I guess it was some kind of scam...
Once again, thank you for taking the time to read and reply!
A file system extension to move the operating systems to SD card would not be a good idea, the performance would be very slow as access speeds are not good.
As for the htc album cache eating alot of memory there is the possibility to use some of the phones RAM (as the HD2 has way more than you need) as a virtual storage card or RAMDISK. You can move the HTC album cache, opera cache and manilla/windows temp files here.
This has the advantage of removing all these junk files everytime you reboot your phone and also making opera and the album run faster as writing cache files to RAM is much faster than writing to ROM
