Corrupted 7z file

Question

I recently wanted to try out Fedora. So I transfered all my files to it via USB. Then I got frustrated with it, placed all my files in a 7z archive and then copied them back to the drive. Now, every time I try to open the archive, "an error occurred while loading the archive" Thanks for your help

[edit] There is no password on the archive.

ls -alF file.7z

Solution

There are two 7zip programs in the Ubuntu archives: p7zip and p7zip-full. Make sure p7zip-full is installed. Reboot to make double sure.

Otherwise, try copying the archive to a Windows recognized filesystem on a pen drive or something and try it on a Windows machine with 7z installed.

If the above procedures do not work, the .7z file is incomplete or damaged and must be redone. If you deleted your data, unfortunately, your only hope is to recover as much of the most valuable pieces as possible from the medium you got it from in the first place.

Maybe pointing out the obvious, but are you sure 7z is actually installed? Although the archive manager can work with 7z files, it will only work if you install it. That isn't the case by default. So maybe your file inst corrupt at all.

Yes, I installed it right after I installed 13.10.

(To do that, Using the terminal just cd to the directory where your 7z archive is located and do: 7z e YourArchiveName)

I don't believe in irrecoverable data (except for a purposefully destroyed). It's there, it's just not built correctly. You don't throw out a castle b/c the front gate has been knocked down. You rebuild it.

@KI4JGT unless your servants have no idea how to rebuild it.
