How do I fix opening this file?

Alright, so I recently saved a game I was working on and shut down my computer. The next morning, I turned back on the computer and tried opening the file, but it showed me an error that said "Unable to open 'Desktop/Games/Game.capx' for unzipping". I feel kind of dumb, but I don't know what to do about this. Is there a way to fix this? Its located in a couple of folders, but they arent zipped. What do I do?

A .capx is basically a zipped file format, so can usually be unzipped by most programs, such as Winzip, 7zip etc.

If your .capx is actually mangled, then look for the automatic saves and backup files in the same folder.

You should be able to just change the suffix of the latest to .capx and open it in C2.

Ah, the backup file worked. Thanks!
