Hey everyone,
I encrypted some avi files months ago. Before I reinstalled Windows XP Pro, I moved all files to an external hard drive. Now I cannot play any of those encrypted files with media player. I can't delete or move them. I can't decrypt them either. This is the message I get:

'Windows Media Player cannot access the file. The file might be in use, you might not have access to the computer where the file is stored, or your proxy settings might not be correct.'


Does anyone have a solution? I tried a few things I read on the internet but none worked. Oh yeah, the name of the files are highlighted in green.....I guess its an indicator that the files are encrypted. Please help me. Thanks in advanced.

Bad news I guess.....I installed Advanced EFS Data Recovery 1.0. When I ran the program it identified the files as not decryptable. Is this the end or is there some other solution?

What did you use to encrypt the files with? Any specific program?

Sorry to resurrect this topic from April but I'm having the same identical problem. I have a bunch of files highlighted green after my reinstall that I don't have access to. I don't think I used a special program to encrypt with.. just standard windows xp pro service. Like hidding the files.

I moved all the files to my Maxtor onetouch4 500gig external drive in one cut and paste effort, and I'de say about 40% of the files are highlighted green. The other files are regular black, which work perfectly. The files that do not play are .avi files... either divx, xvid, etc.

I really don't know what's going on here. Help!?!!

I've tried that, but with no success. Any other tips?

I have some very large and valuable vids sitting on this external that just wasting space as I cannot even delete them. It's like their corrupt but the correct file sizes are still showing up...as well as the other 50% of vids that do work. I don't wanna give up on this.

Thanks again.

Something I should add...

When I copyed my files to the external it asked me if I was sure I wanted to move the read-only files. It asked me lots of times and I just clicked 'yes'.

I was unaware of the phenomina it would bring about. So... is there any chance of recovery of such stupidity?

I've heard (though I've never tested this) that files encrypted with Windows built in encryption utility must be decrypted by the same user with the same password that initially encrypted them.

If you aren't using the same username & password combination on this new install, try changing your username or password (as appropriate) to the combo you used at the last time you were able to access them. Then try to access/decrypt them.

This is one of the reasons I avoid using the encryption feature of NTFS: it's actually too good! I would recommend using TrueCrypt in the future.

If you used EFS to encrypt these files, then recovery may be possible. This google search will start you off in the right direction: http://www.google.com/search?q=recover+enc...lient=firefox-a
