Encrypted jpg files??

Few months ago I scanned some pictures. I signed in just as always, scanned, edited, (they opened then) and now months later when I try to open them, they won't open. I can't even rename, copy, send them by email or do anything else to them..

My profile b0rked in time between scanning and now. Has those files been encrypted automatically and now as my old profile is deleted, Windows doesn't let me access those files at all?? And just to make everything a bit more fun, I'm at work and can't install any new sofware!!

Is there anyway I can remove that encryption, WITHOUT INSTALLING ANY SOFTWARE? Even sending them to my own computer would help.

Are you using linux....

If so, can't you sudo -s and chmod 777 the files?

Ahh, I'm thick, just saw you said you're using windows....


I believe Windows does support file based encryption, but I've not actually tried it, sorry...

...one way of getting round it may be to boot with some kind of linux recovery CD and steal the files that way?

Assuming it's Windows EFS encryption at play, when you created the encrypted volume, did you also assign a recovery agent and backup the agent's private key somewhere?

Or it might not be encryption at all. Right-click on the file's containing folder and choose "Properties...", and look at its security settings. It might be the case that your new user account simply doesn't have access rights to the file / folder. In that case, login as an administrator, take ownership of the file / folder, and grant access rights to your new user account.

either download a copy of knoppix (bootable linux cd) or (i think) disable simple file sharing

I wish I could use Knoppix or something like that, but I think that administrator wouldn't let me to. Damn if I had the administrator access.. Well I have to tell her to try to take ownership or something..
Thanks guys..

Yes I know that but this is a big network. If I just start using different booting cds or disks without administrators permission would she like that? I think not and I don't want any trouble just because I wan't few pictures to show. People are careful here, maybe even too careful..

Ask them, if they say no, unplug the connection to the network while its off. Turn it on and load Knoppix. Burn it to CD or dump it on a flashram drive. Done

sounds like a file permission problem rather then an encryption problem. login as administrator to access the files.

Now that I read it again, Lapikas seems to imply that he has no administrator access.

In that case, either ask an administrator for help, or help yourself.

I don't have administrator access. And the administrator is an idiot.. I gave her same advice as Griffinn and KXRM gave me. Now it's not my problem anymore.
Those pictures were not personal pictures and she really needs them..

so they were encrypted via windows' built in file protection? the one where each person's documents are "Made private"?...

easy way around it: use partitionmagic to convert the hard drive to fat32... that'll remove the encryption... then back to NTFS...

voila. figured that out when i "made private" about 80 gigs of music and then my system hard drive got fried... the music was on the second drive, but i couldn't access it even after installing a new primary drive without converting to FAT32 first...

Weeeeeeeeeeee
