Hi,
I was wondering if anyone knows of an app that lets you encrypt files or folders on the storage card?
I know there's encryption utility under settings, but it's for all files on the storage card and will not survive a hard reset.
I'm looking for a utility that lets you protect files with user/password, one that will survive hard reset and will let me access the files even after hard reset. Preferably without 'packing' all the files into a single encrypted file - just leave the folder structure as it is, but ask for username/password when I try to access it...
Anyone knows something that does that?
Thanks

Hi All,
I recently installed the latest MightyROM (2-10-10) but now cannot get my Exchange OTA ActiveSync working for my corporate e-mail.
Did some digging, and figured out that the issue is that my corporate Exchange security policy requires both devce and SD card encryption on any devices connecting to OTA ActiveSync.
Further searching revealed that SD card encryption was *removed* from MightyROM starting a few versions back.
I know for sure that my device is missing both encfilt.dll and mencfilt.dll which seem to be required for SD card encryption (the details of which I'm not familiar with).
So the question is: Is there any way at all for me to add SD card encryption back to the ROM, preferably without having to re-flash?
Can I somehow get copies of encfilt.dll and mencfilt.dll and register them on the device?
Any ideas / CABs that might help is greatly appreciated!!
Many thanks in advance.

regsrvceGUI.exe I believe is what you can use to register the .dll files. I however can not get it to copy out of the windows directory...
I did find this reg key and you can try to set it and see if it flies... Remember to do a backup and all that stuff. (I'm not 100% it applies to the SD card or not). And I do not know if you need those two files for it to work so use at your own risk.
[HKEY_LOCAL_MACHINE\System\StorageManager\Filters\E NCFilt]
'EncryptByDefault'=dword:1 (change from 0 to 1)
Soft reset
I will keep trying to figure out how to remove this file from my device so I can share it with you.
If that doesn't fly, then maybe you need to go back to an earlier rom. ???
Thanks! (for your response here and on PPCgeeks
That reg tweak you posted makes the UI appear like SD encryption is enabled, but it's not actually running (as key files are missing).
You're right, I may have to downgrade my ROM, but hoping there's an easier solution!
Which ROM version are you using?
Thanks.
BTW, when I try to sync without SD Card encryption, I get the 85010013 error code in activesync, which is pretty generic -- not sure if this info helps.
Hoping someone can chime in with more ideas.
I just found this post and was wondering if you solved your problem? I'm getting the same errors but I can't find out how to encrypt the entire handset just the SD card.
Hi,
Does anybody has solution for this?

You could try a hard reset...maybe that might work but you will lose all your files stored on your device. However you could take out the storage card that way the files on the storage card would be safe.
What files are you trying to save?
Yes i think what he means was to take files (backup) from locked phone, if you hard reset it, you'll loose anything except files that stay on storage card.
If you're only talking about the lockscreen, then you will have to perform a hard reset to get around it. Hopefully you haven't encrypted the files on your SD card. If so, you will loose those too. Next time, try a different lock program like S2U2 for a better UI as well as no real problems with it forgetting your password. You can also get around it if you forget your password.
This is a common problem with this phone and why I will never use a password on it. Not sure what the cause is, but a hard reset is your only option.
This matter had also making me curiously, searching whole source in the net, still the answer is no way except doing hard reset.
Hi there,
I'm programming something for Windows Mobile 2003. It basically removes and creates files around. One of the files it deletes is special file.reg, which is normally picked up during the hard-reset.
The file gets deleted using "DeleteFile" and very soon after, I force a hard-reset.
The problem is, the special file.reg is deleted from the file system tree, but it is apparently still available from the hard-reset.
I was wondering if there was another function I had to call to "flush" the file system? If not, I need to find a good trick to 1) enforce the file deletion (like rename first, then delete) and to 2) flush current ghost files left around.
The file system on those persistent drives are fat12 and/or fat16.
Thanks in advance for any input,
Simon
The hard reset returns the machine to its first power up state. If 'file.reg' was part of the original build, then the hard reset will restore it from ROM.
Also any programs you have installed to run on startup, will also be lost, so it is going to be a little difficult, if not impossible, to get rid of this file programatically.
Right, but I'm not talking about the ROM.
I'm talking about the persistent memory which are mounted as \Platform and \Application on this device. Those are FAT12 and/or FAT16, and files deleted (normally) do not come back.
In this case, the files are not coming back, they are not hidden either, but the hardreset process is able to pick them up somehow.
I mean, I call it the problem of the "Ghost files", because they are supposed to be nowhere, but they are found during during the hardreset.
(The files are not recreated, they are still not there, but their contents gets loaded. The info in them cannot be placed in ROM as it contains stuff that changes often)
They come back after a hard reset because during cold boot, they're being copied there from the rom or being created by the system. You may be able to delete them afterwards, but the only way to prevent them from being formed will be to re-cook the rom and stop them from being copied/created during boot-up.
The files DO NOT come back, it's gone, I cannot re-delete it. But somehow it is "read" by a program during the hard-reset.
This file is not part of the ROM, it's part of the persistent memory that doesn't get wiped out upon hardreset but is read-write.
I need to wipe out the ghost file that is stuck on the read/write partition... and I need a way to avoid these being created!
I understand that, but clearly the file is being created (or copied from rom) during cold re-boot, otherwise you wouldn't see it coming back. There isn't going to be any easy way to prevent that, unless you can re-cook the rom, or include some sort of user customization that would delete the files prior to using the device. There are lots of ways that the rom could create the files and put them onto persistant storage.
Hi Farmer Ted,
this is not a ROM issue, recooking the ROM will not help. The problem is a FAT12 or FAT16 filesystem that has bogus data in it.
The problem is most likely a bug in the program that reads the persistent folders... It probably reads it in a way that goes around the change made by DeleteFile()...
Changing that program is not possible (in ROM and I don't have the source, it's also necessary). I just need to make sure it can't find the file I've deleted on the persistent directory (not in ROM).
I have a live demo unit of note 2. Unfurtunately i can't delete anything from the internal storage, because it says taht the storage is protected when trying to delete them from the PC, and simply can't delete file when trying from the phone itself.
Solid explorer shows that i have both write and read permissions, so other then that, where else i should look into?
I can write new files to the storage just can't delete the ones that were there by default.
You should try doing a factory reset. I don't have the note II but its still an android phone. If that doesn't work, check in the security settings
Sent from my Nexus S using xda premium
i've done that, doesn't help.
Don't see anything in security that might help either.
Newbie question, forgive me if it's dumb. I have a Galaxy Tab T310 that I just rooted because I wanted to be able to get around the SD card write issue. BUT, the real problem I have is that I want to simply copy movies from my desktop to the Tab via a USB cable but the Tab keeps erasing the files. It doesn't erase the directories I create on the SD, it just erases the files IN the directories and often the subdirectories. Sometimes it erases them as soon as I copy new files to the SD, sometimes when I reboot the phone. But it always erases them.
I'm assuming this is related to the Android security effort to "protect me," but I don't know how to keep it from happening. Will one of the root apps like SDFix keep this from happening? Again, I'm not talking about apps being able to write files to the SD, I'm just talking about me being able to write files to the SD using a cable and then KEEPING the files from being erased by the Tab. Thanks for the help!
Auto-delete files
Can anyone point me toward another forum where I might find an answer to this question? I thought this would be the best place but apparently I am the only person who has ever seen this problem. This makes me wonder whether there is another problem with the tablet....

You might try downloading an SD Card Fix app from the Play store. There are several of them. KK messed up the ability to copy to the Ext SD card.
If you're rooted, then download ES File explorer app. Run it and hit your menu button. Scroll down the menu and make sure Root Explorer is checked.
That's all I can think of that might help
