[Q] astro file manager questions - Nexus 4 Q&A, Help & Troubleshooting

This is my first android phone and have to admit i know very little about the technicalities of mobile phones although I consider myself very knowledgeable with anything to do with computers.
I recently installed astro file manager so I could move, rename file and folders. While exploring the file manager I noticed and mnt folder containing an sdcard folder, another folder called sdcard in the main directory and the emulated and sdcard0 folders contained within the storage folder. All the folders seem to have the same files and folders. Could anyone tell me the difference between the four folders. Sorry if it's a very noobish question.
Also can any one tell me why whatsapp images remain in the same folder in gallery although I have moved them in the file manager
Thanks

It's there for other devices. Tablets in 4.2.x has multi users. So storage would be separated between the two. It is called emulated to emulate the old folder naming scheme before 4.2.
Just ignore it, shouldn't make a difference.
As far as your folder and whatsapp, it needs to research it's contents. Restart your phone or plug it in via usb and unplug.

So which folder should I use to rename, change all my files around safely? sdcard0 in the storage folder?

Folder Structures in SDCARD

Hi everybody!
I just got my DHD and already root, clockwork, changed rom, etc. However, my problem is related to the directories structures inside my SDCARD.
I have 2 questions:
1- I moved some apps that I have in my main memory to my SDCARD via App Settings. However, when I go to my sdcard in windows explorer, I don't find these files. I'm not sure then if is really moving to my sdcard. I just realized some new folders, but they are empty. Does anyone knows what I'm doing wrong?
2- The second question it's linked with the first. I would like to organize in my SDCARD a nice folder structure. Something like:
/
/Songs/
/Photos/
/Documents/
/Backups/
/Games/
/Apps/
And then if you go inside the Apps folder, you have another folder with the name of the application. Pretty much like Program Files folder in Windows.
Is this possible? For Songs, Photos, Documents, I created a folder and it worked. But what about for apps and games that I got on the market?
My SDCARD has also a lot of folder/files that were copied when I put the sdcard on the device. I don't know if I can delete that. Any idea?
Thanks for the help in advance!

{HELP}lost in LOST.DIR

i'm not sure if i'm on the right place for asking this but i have no other place to go.
when we put an sd card a folder with the name LOST.DIR is created
once when i inserted a sdcard that is not the usual that i use, i found that many of my files, such as music, pics and docs, are missing and a large number of files are iin the LOST.DIR folder. i suspect that those are my missing files, however they very far from being usefull.
i would just like to ask is there any hope in recovering those lost files?
I hope you know how to unmount your SD card before removing it from your phone.
Well I know about that
Settings>sdcard and phone storage>unmount sdcard.
Is there a chance to retrieve those lost files, or are they gone for good?
Sent from my GT-S5360 via freenet
the files are still there in LOST.DIR
You have to add the file type back to the lost file. I believe you cannot get back the name you given to the file or dates.
I got many large files size in LOST.DIR if the phone fail to boot, I dont know if this right or not

LOST.DIR????
i always deleted tihs folder.
but always there again....
and i never have bad experience after i deleted that...:highfive:
LOST.DIR can (gently) describe as the TEMP folder for Android, as in the% System% Windows / Windows / TEMP is the case.
you can delete it 10000000000000,it comes back.so its not necessary to delete these files it comes back.

Rooted nexus 4: file structure

I'm new to android, I apologise in advance if this is a stupid question:
I rooted my Nexus 4 and was browsing the memory using astro file manager. I don't quite understand the file structure on my phone as to what files are safe to fiddle with and what are not.
For example there are three folders with exactly the same content: storage/emulated, storage/sdcard0, sd card. Why?
Am I right thinking all the folders under the root (home) directory should be left alone? But ones in the above three directory can be deleted? They seems to contain app data.
I want to clean up my phone memory so that's why I'm looking for files to delete.
Thanks everyone

Yikes! I removed the "storage" folder in storage/emulated/0/. Help!

Great. Now my entire virtual SD Card has been wiped! Don't delete the storage directory in the root of your virtual SD Card (/storage/emulated/0/) or (/storage/emulated/legacy/). Watch out!
Now, I'm wondering if I can somehow gain access to the files if I recreate this folder. From what I remember, there were a number of nested folders within this "storage" directory.
Can someone give me the dir structure of your "storage" folder? Thanks!!
EDIT: This is how I did it. See post 6. Stay away from your "storage" folder while browsing your phones sd card over MTP at the computer!!!

I'm not sure if this is what you are asking for. If it is, then yay! If it isn't, please ignore.
/storage/emulated/0/
/storage/emulated/legacy/
/storage/sdcard0/

Hey thanks for that, but I'm pretty sure there was a folder called "storage" in /storage/emulated/0/ (or the same location /storage/emulated/legacy/).
So, what I'm looking for is what the folders are in *that* folder. And it should look something like the following:
/storage/emulated/0/storage/...... <---------- these are the folders I'm missing, and there most likely is a symlink in there. I think if I can just recreate that folder structure and recreate the right symlink there, then I might be able to get my photos back.
Thanks.
You're saying there is a "storage" folder in /storage/emulated/0 or /storage/emulated/legacy? Mine only comes with these 2 directory, and /storage/sdcard0 is a link to legacy.
Now you still have that 2 directory but can't find any of your files inside?
You deleted the storage when hooked up on your PC yes ?.
The storage folder your referring to only shows when browsing your folders via your PC so you could try recreating it via your PC again but I seriously think its gone mate. I accidentally deleted this folder too once but I always have regular backups on my pc.

Yes!!! Thanks for this post! I was indeed cleaning up my "sd card" from the PC (over MTP). And, I noticed a storage folder at the root of the SD card. In fact, it's there right now! If I browse the contents of the SD card on the PC, there is a storage folder there with only an empty "emulated" folder in it. I've never noticed it there before, so I just deleted it. Suddenly, I couldn't access anything else on the sd card from the PC. I thought, that's weird. Sure enough, everything just vanished!!
WORD TO THE WISE: Stay away from that "storage" folder at the root of your SD Card when browsing its contents over MTP!!!!!!!!
why not just do a factory image flash? userdata.img should contain all the folders and locations you need to restore it properly.

Oh, there ins't a problem anymore. I just thought that the "missing" symlinks had something to do with my wiped sd card. But, it turns out that the missing symlinks aren't shown in the default CM file browser, only in other file browsers. They were there all along.
The kernel of the story has been solved as I now know how I wiped my sd card.

There is no way to get the files back, I deleted it once when connected to PC because I didn't recognized the folder and it was empty, so I deleted it. Then I tried for a week in every forum to found an answer, but there is none.
reflashing your current rom or any other rom would have brought everything back to how it should be. a deleted my whole system once, then just relashed my current rom at the time, and all came back.

Oh, I got most, if not all my photos back. There is a great link which shows you how to transfer your entire userdata partition to your hard drive and search for recoverable files. Alternatively, you can also use the app diskdigger and send your pics to your PC using coreFTP or other FTP server. Both methods recovered about the same number of photos. So, yeah, a reasonably good ending.

Not in my case. That's the first thing I did. I thought, it's just a symlink, right? Well, not really. It's not really a symlink on a different partition. Again, it is only created during an active MTP session and ONLY visible on the PC. And, as soon as you wipe these seemingly empty folders, all references to the files are lost, as the system begins to slowly re-populate the space, which is really at /data/media/0.

I know it wouldn't bring your files back, but it would restructure your storage partition properly so you could start from scratch, rather than recreating all the folders manually.

? No one is doing anything manually. Did you intend to reply to me? The missing symlinks referred to earlier have nothing to do with it, as I discovered and reported a few posts ago. Again, there is a "storage" folder at the root of the SD card only visible at the PC when connected over the MTP protocol. When this folder is deleted, all is lost immediately, even by re-flashing a ROM. Hope that helps someone to avoid deleting it and consequently all their virtual sd card files.

Hey how did you do it? Which third party file browser did you use? I have done the same thing..
Check /data/media/ those folders are just linked to /data/media/ anyways. All your stuff should be there unless if you deleted the entire data partition

The problem is that if you are browsing the SD card contents from your computer (while the phone is connected), a folder appears there that otherwise is NOT present while browsing the card's contents from the phone, while the phone is NOT connected. I forgot which folder it is, but I believe it is called sdcard0 or some such at the root of the SD card. I have no idea why it appears, but if you delete it, you have deleted the entire contents of your SD card. And, yes, you have lost everything unless you are able to acquire a special tool to recover the contents, but if you have done so, don't do anything with your phone, as those contents will be overwritten by new files.
In so doing, I had originally thought that there were symlinks that were also deleted, but that wasn't the case. The symlinks were still present as viewable by ES File Explorer, but not with CM's file explorer. In any case, all my files were still lost, but I was indeed able to recover the majority.
Edit. I used Diskdigger in the Play store. And it worked pretty well. The other option is linked in this thread above.

Yes. First, either turn your phone off or do VERY little with it, as those files could be overwritten.
I had surprisingly good success with Diskdigger. It was able to recover most of my photos, although some were a bit "damaged", as in only half of the photo showing, and some other oddities. But, at least it was better than nothing. You will need root access for this sort of thing.

Thanks a lot!!! Im using disk digger and I already see a lot of my images turning up
Just one other doubt, if I were to use the link to guide which you posted which allows to mount the VHD as a USB storage, does that allow me to recover other files too?

Internal Storage vs Storage Emulated - App Can't Find storage/emulated/0

I upgraded to a Nexus 6P which is now rooted thank to the help of several people here on XDA. I have an app that backs up to /storage/emulated/0/Droid90. On the 6P, when I view the folder structure, I found a /storage/emulated under /Root, but no /0 folder. I tried to create one, but X-plore wouldn't let me do it. I suspect that some of these folders are just pointers to the real storage locations, but I've scoured the web and here and can't find what I need. Is there any way to create a new /storage/emulated/0/Droid90 folder on my 6P that this older app will find? I've contacted the developer but he's been incommunicado since at least September (based on his last Google+ posts and lack of response to questions after September from others). As further info, I think it's forcing the backup/restore folder onto an Sdcard (maybe; maybe not). Could I create a storage/emulated/0/Droid90 folder in my emulated /sdcard (internal storage) folder on the 6P? I'll try, but not sure it'll work. Any other suggestions? Thanks!

BTW, I tried created an emulated folder and it worked but the app still doesn't recognize the location even when I put my backup file there. Anybody else have another suggestion? Thanks!
