Hi,
I just noticed very strange behavior of my Nexus 4 and my Windows 8.1 Laptop, when I'm looking at my 'sdcard' directory on phone using Root Explorer or ES File Explorer. For example I have some files in my Download folder, when I' deleted them, they appear to be gone forever. Folder properties says there are only for example 4 files - 14Mb, but then, when I connect my phone to my Laptop with USB cable, and check the same folder I see those deleted files, and folder properties says there are more files taking more space... I don't know what's causing that, and i think it's really strange... I'll attach some screens to show you what i mean.
I'm sorry that screens are not in English but you should be able to figure out what i mean:
This is what I see on my Laptop:

This is what i see on my Phone:

After you delete the file on the phone, you need to let "media scan" run so it can update the files index, only then connect it to your computer, so the changes will be reflected. This is done automatically if you just wait a while or reboot the phone and give it a few minutes to scan.
If you delete files from the phone while you have the phone plugged in, it won't get update soon enough. If you delete the files from the computer then more than likely it will get updated on the phone aswell.

hey all iv noticed this a lot with the stock 2.2 rom on my POV Mobii tegra 2 (advent vega rebrand).
e.g i uninstalled a game called jelly defence, then tried to install an updated version of it. the install fails saying aplication not installed.
ok so i then tried to reinstall the first version i had working on the tablet, and that also fails to install saying again application not installed..
why would this be happening? iv noticed that it happens on a fair few number of apps that i install, then uninstall, then try to install again and they fail to install.
installation is done via apk file from sd card. even tried over wifi and still same error.
I know this might sound rude, but did you try Google?

ahh, could be something to do with the certificates or the AndroidManifest.xml file.
where is this file located so that i can check its permissions?
This might be a tough nutt to crack...
"AndroidManifest.xml" file is inside .apk files.
ok i managed to fix the problem. i mounted my sd card to the pc with card reader, and in the android.secure folder there was a file called smdl2tmp1.asec , i deleted that and now the app installs fine. got both jelly defence and few others installed with no issues.
strange how i cant see that folder on the tablet itself because its hidden. need an app to see the folder and its contents directly on the tablet so i can delete it again if needed.
Yeah, folders and files with a dot infront of their names are invisible.
It's a Linux thing!
Glad you got that sorted out!
is there no file manager app that can see these files directly on the tablet?
Just tried "iFileManager" app I got with stock tablet software and it can see hidden files/folders.
I also tried Root Explorer and it can see hidden files/folders, but this is a paid app.
Astro File Manager can also see hidden files/folders, but you need to go into Preferences-->Look and Feel-->and enable "Show Hidden Files" option.
Maybe your current file manager app also has such an option?
Hope I helped, and don't forget to give a thanks!
ahh, i have stock ifilemanager, but i dont use it, i use ES File Explorer since i can access my LAN shares with it easily over the wifi. will give ifilemanager a go in few mins time.
thanks again.
just checked ifilemanager can see the folder but it cant see any of the file which are inside the folder.
Just checked some "hidden" folders myself on my tablet.
Some have files / sub-folders inside and some don't.
Not all folders need to have files inside.
but when i check the folder on the pc via sdcard reader, there are files in the folder.
cant see them directly on the tablet, but when connected to pc i can see the files in exact same location.
Hi, I downloaded a big iso file (say file x) on my nexus 4. weird thing is I can't see the file from my pc when I connect my phone to my pc. I can see the folders on my phone but can't see the folder (say folder f1) that contains the file..
Even more weird thing is when I moved some file in the f1 to a folder (say f2) using Astro file manager that can be seen from my pc. I can see the file in f2 on my phone, but it's not on my pc.
Then I renamed a file (file y) in f2 in Astro. Both fy and f2 can be seen on my pc. But on my pc I can't see the name of y changed.
In short what kind of changes I made to my files on my phone, nothing happens on my pc. I have unplugged the cable and repluggd it but the situation is still the same.
Also, I can create folder/file from pc and they can be seen from my phone.

All right, it's suddenly just fine. No idea why.
Was going to say it could be due to the horrible MTP that Android now uses instead of Mass Storage.
MTP Limits large files from being transferred to and from the device.
(and only shows some folders, usually the basic Music, Downloads, Pictures, etc - and folders that were created on the device via the computer)
But since it just showed up, I have no clue...
I have no problems with MTP, all my folders and files show up on my pc. Can also transfer large video files without a problem. The size limitation by the way is 4GB.

Sometimes you may have to reboot the phone to be able to see the files. Works for me. After download some files I can't see them immediately, have to reboot phone then plug in and files will be there.

I've had trouble with MTP, unable to write certain files... So I have to Zip them, copy them over, then unzip them from within Android. And I made some Backups of my Apex Settings and such, before uninstalling the app, when I plugged the N4 into my computer the location where Apex saved the file did not show.. Once I finally just saved them to my Google Drive from the phone, I was unable to copy them back over to the N4 (hence the reason for needing to ZIP them) - Also I recreated the Apex settings folder myself via Windows Explorer in the Android Folder of the n4 but Apex was unable to find it. When I clicked Backup within Apex, it normally will inform you of an overwrite if backup files already exist, but this did not happen.
I have the basic folders appear in Windows Explorer (Alarms, Android, DCIM, Downloads, Movies, Music, Notifications, Pictures, Podcast, and Ringtones) ... The Android Folder (where Apex saves its backups) would only display a few select folders (those related to media) so the Apex Backup folder is not visible in Windows Explorer...
Anyhow, I'm certainly not a fan of MTP... but will read the article you posted and maybe it will help/change my view
cannot transfer files via usb- stuck in "calculating the time required to copy files"

Try copying smaller groups of files at a time.
Ex
The Android folder will cause this issue when trying to copy it and all sub folders at once by simply selecting the Android folder and copying it.
Instead, create an Android folder in your destination folder (where you are copying to) then create each subfolder as well (data, obb, etc). Then just copy each folder within data, obb, etc, individually. It's a PITA, but this is how I've always bypassed the problem.

did it work ?
I just had the same problem. It may be some sort of corrupted folder. Here's what worked for me:
I think it started when I tried copying multiple folders instead of just one at a time, as I usually do. I cancelled because it was taking so long.
After that I constantly got the exact same thing you describe ... Had to kill Windows Explorer over & over.
What I noticed: Windows Explorer could surf into other folders, but clicking on one particular folder always hung Explorer.
So, I went in on the phone's My Files app, and did the following:
1. Looked at the folder - It appeared fine.
2. I copied all the files out of the folder
3. Deleted the folder
4. Recreated it
5. Copied the files back in
It took a few tries, but after that everything is back to working normally.
Hi,
I'm on stock everything, havent done anything to my phone.
Here's what happens, I plugged my nexus 6p on my pc.
I am expecting a few more files and folders in the Downloads folder, but I only see a few in the PC. Screenshots attached.
EDIT: As you can see, kali-linux-2016.1-amd64 and NBA_2K11-FLT (I downloaded because of Jordan Mode LOL) weren't shown on my PC. Please help me.
EDIT 2: It turns out this is a code issue on Android itself. A temporary work around would be to move the folder/file on Android, using a File Manager to a different location so that Android can scan the folder/file.
When I copy a file from my computer to my phone, the "last modified time" of the file transferred to my phone is changed to the time when the file is successfully transferred to my phone.
Keeping this metadata properly maintained is important for me because I use a software called FreeFileSync to sync files between my PC and my phone. The last modified time helps the software to keep track of files.
Is there a way I can get around this issue?
PS. Files copied from my phone to my PC have the "last modified time" intact. Here's an error message in FreeFileSync in case you want to have a look.
Edit: It isn't just mtp. Using adb to copy files also doesn't work. The last modified time is still changing to the time when the file is transferred.

Forgot adb existed. I will try to find some adb file copying gui software after I get home.

I have tried adb push. It's the same as mtp. The last modified time changes to the time when the file is transferred.
So you mean your problem get fixed, am I right?
