Problem with large games not being able to decompress their data. - General Questions and Answers

I've got Cyanogenmod 12.1 on a Galaxy S2 i9100 and the storage is a pain in the arse to be honest. I know the switch from FAT32 to EXT4 with JB or KK was supposed to be better for security, but for access it is abysmal. I can't copy large folders to the internal SD or else half way through the process Windows will tell me the device has been disconnected, I also can't install large games like Football Manager 2015 or Sims Freeplay because after they have downloaded their zip/rar and try to extract it they just crash (even when the phone is not plugged in), and if I copy the downloaded archive to my PC and extract it there it will crash when I try to copy the extracted folder back to the Android/data/ folder.
Is there a fix for this? I had no problems using FAT32 for many years, but now I have an internal storage that seems to choose when it wants to be visible to my computer and will decide to unmount(?) when something is being copied to or extracted on to it.

Nobody have any ideas? I've googled like mad but can't find this problem anywhere. It has to be ext4-related though because apps and games have never had a problem uncompressing their data until after 4.4
This is annoying the bejesus out of me because Football Manager keeps me sane on the train :/

Not even 'adb push' works! I did adb push with the -p switch to see progress and everything is fine for a minute or two and then
failed to copy 'xx.xx' to '/sdcard/data/xx.xx': Read-only file system
This is officially driving me up the wall now, surely someone has an idea of why my internal storage stops extracting an archive or copying files after a short period :/

[Q] Urgent - need help with an issue on my xoom.

Previously I was using cm9, after that I upgraded to cm10. I wiped data, wiped cache in cwm recovery.
After that, I tried xfering some files over to my tab, it looked like this
i. imgur.com/T3LAU.png
From this picture, it can be seen that my internal memory has files and is not empty
yet when I enter the folder
i. imgur.com/Mn7lR.png
Completely empty, cant be seen.
Even after trying to copy and paste files in, only the new files appear, can no longer find my old files.
Can anybody help me? same thing for the SD card. SD card only detected when I removed and plugged in with external usb card reader to my pc.
(I can't post images yet, hopefully someone with >10 posts can hotlink it for me).
Really urgent because I have to use it for my lecture notes in school.
If you want a workaround on this issue, you can use a cloud storage app. For example, dropbox (go to my signature and click the dropbox logo) can allow you to transfer files without even plugging your Xoom into your computer
Managed to solve the issue by doing a complete memory wipe on my internal hard disk but backing up important files before hand w dropbox as the files are still accessible with astro.
No idea how this happened though.
It's called MTP. Hahahaha in other words windows sucks.
Really what happens is the file list directory isn't updated so it doesn't show up on explorer. I don't even use explorer, I just use ADB push or pull.

Internal memory is FULL with NO APPS?! HELP

So i've been trying to research this problem for hours now. Ive jumped around a bunch of different roms since owning this gs3. MIUI 4.1 - Aokp 4.2.1 and currently synergy 4.1.2. I think since flashing aokp 4.2 that i get that "0" file when looking for files and such. I can tap "0" like 4-5 times to finally get into the files i want. I'm not sure if this is where my problem is coming from?
Let me say i don't have ANY backups. Im running clockwork and wiped,reset,cache all of that multiple times. I have ZERO apps installed and only a handful of pictures. My internal memory says its full and i get a warning at the top saying that my internal storage is to the max and that some programs might not respond. The bulk of GB used is in the "misc" folder. I've seen other people with this issue but it seems the only fix is to re-format the internal memory and LOSE EVERYTHING. I'm sure someone here can help :/
You delete all those roms you downloaded after flashing them?

Install Disk Usage (if you have the space <grin>) and see what it says is taking up the space:
I feel as though it has something to do with the emulated "0" folders. I have literally 5 of them. I downloaded disk usage and it shows 5 different "0" folders.
Out of pure frustration, I went into the second "0" folder in file manager and deleted it. That in-turn must of deleted the other "0" folders? That free up 7 GB. My pictures and videos are still there but im wondering what else it deleted? It seemed like things would get stored in each of those "0" folders seperatly.

Ah, yes, the joys of 4.2. I've never flashed a 4.2 ROM, so take what I say with a grain of salt. It's my understanding that when you flash 4.2, it takes everything on the internal SD (/data/media/ folder) and puts it into that "0" folder (part of that whole separate user accounts "feature"). So, if you've installed, let's say five, 4.2 Roms, then that info will have been copied 5 times and put into nested "0" folders.
If it were me, I'd run a nandroid and put it on my external sd. I'd also run a TiBu (under preferences you can switch default location to external sd). Once you're sure you have those, I'd copy whatever data you want to save from the internal (DCIM folder, music, etc) and move it to computer or external sd.
Have a copy of synergy on the external and go into CWM and wipe the internal SD card (mounts -> wipe system, wipe data, wipe cache, wipe internal sd), then reinstall synergy, restore from TiBu and you should be golden.

That sounds about right. Man this right here is enough for me to never want to go to 4.2 until I have too. Is the easiest way to transfer all my files to external SD through a computer? Where abouts in the phone do you transfer/or assign your files to an external SD?

Have you installed Android SDK on your computer (ever used adb commands via command prompt)?
Edit: if you open up your phone in windows explorer, you should see 2 folders: Phone and Card (or something like that). You can drag the files from Phone to Card and they'll be on the external SD.

Gotcha, i'll try that. I have a feeling once more people start running 4.2 they're going to run into this problem as well.
If you do have the SDK set up, a faster way to do it (if you're moving a butt-load of data) is to open a command prompt on the computer and navigate to where you want the data. For instance, I use C:\Backups. I'll then create a 2 folders within Backups (one for internal and one for external sd) and give them the date as a name. For instance, C:\Backups\Internal_2_5 and C:\Backups\External_2_5.
Then I'll be in C:\Backups and issue these commands:
Code:
adb pull /data/media/ Internal_2_5
adb pull /external_sd/ External_2_5
Depending on how much data you're moving, it could take awhile. Now, you could pick and choose what you want to pull:
Code:
adb pull /data/media/DCIM Internal_2_5/DCIM
would only pull that DCIM folder.
When I dump all of it, I'll wipe everything, install my rom, get it all up and going, then go through each of those backup folders and delete the stuff that's not "mine" (ie the Android folder(since your new rom built it's own folder), etc), then I'll push it back to the phone:
Code:
adb push Internal_2_5 /data/media/
adb push External_2_5 /external_sd/
Clean wipe, clean install, and all the data that I wanted back.
(fair warning, if your cards are full, that push pull commands could take several hours...)

Files I can't see on my device are taking up space

So the other day while flashing from AOKP to CM11, it came to my attention that there are files on my phone that I can seemingly only see from my recovery. While finding the zip to flash in CWM(Which was in my downloads folder) , I noticed that I have to go through another /0/ folder to get to my actual downloads folder. Before that, there's another Downloads folder, along with a whole bunch of other stuff I must have downloaded a while back. It looks like an old version of my phone's data. There was even a flashable early CM10 rom on there.
I get the feeling this stuff is part of the reason my phone always seems to only have around a gig or two of space open despite it's 16GB capacity and the fact that all of my 40-some apps are under 100MB. It's irritating me to no end to know there are folders I can't access and delete on my phone. Anybody have any suggestions as to how to get rid of this stuff. The several times I've reset and deleted cache to flash a rom seems not to have done anything.
On a side note, really enjoying CM11!
You can thank Google for your troubles. With the 4.2 update Google introduced Multi-User. Basically its like it is Windows where you can have multiple user accounts and each user gets their own profile folder. This is what Google did essentially. The 0 folder is "User1" basically. The files are fine where they are at. They want cause any issues. But if you would like just hook your phone to your PC. Take everything out of the "0" folder and move the file to the root of your internal SDcard. Notice I said Internal SDCard (aka SDCard0) not root of system.

[Q] Nexus 5 storage problem

I installed some games a while back including Badland and Fifa14 and I manually moved the .obb files to my Nexus using a pc which were about 1.8gb combined, then after a while I tried to remove the files manually through the USB connection throughout my pc, the files were gone but it did not affect the storage, I tried everything but I couldn't get my storage back.. I know formatting would solve my problem but I really don't want it to get to that, any help would be appreciated.
@eytch_1 try to restart, see on android with es file explorer or the file still exist, find the trash folder and delete that one. It is maybe hidden but its named like .trash 1000 i believe but its an trash folder i can't say much more since i dont have an phone anymore for 2 months now. Or you must find some app to find big and large files or some trash remover app.
I also had the same problem as you had on my s2 i had my wth moment when that happend and i needed to remove an folder named something with trash and i had my storage back i hope it also works for you.
Also try running fstrim command through elevated terminal emulator. Also use disk usage to see where the space is being used up.

[Q] Copy to storage issue . (*.flac files)

guys anyone any idea on this issue (me vs bacon vs *.flac files) :
- so, when the devices is up on system and connected vie MTP I can not copy *.flac files, it goes up to ~90/98% and stops (sometimes not only *.flac files don't wanna copy, happend with a *.zip file once)
- if I connect my bacon through TWRP MTP (mount storage via recovery), it copies and does it fast as hell, everything copies very fast w/o any issues
any suggestions.?
I tried CM12 Official Nightly and same issue appears...
can it be something from laptop.? than why it doesn't make problems via recovery mount.?
(tried same, and different USB ports 2.0/3.0)
(and also tried FULL Device Wipe, yes even Internal Storage was formatted and "fixed" from TWRP and Phillz)
Thanks
p.s. to be clear, it doesn't give any errors, just won't pass ~90/99% of copy progress, and if a have batch copy of multiple files like *.mp3 and other and a *.flac between them, copy progress stops at "the end of the *.flac file" and won't copy any other files (as like it didn't finish to copy the flac and other files are waiting).
