Hello I have a broken file. It was encrypted(by me) and I did get it unencrypted though I can not remember if it is tar or tar.gz. I believe whichever one it is though is corrupted. I've tried both methods and everything else I could think of for what kind of archive format it could be(7z, zip, etc) and it errors out.

What is a possible course of action to take here? The files on it are not extremely important though they are irreplaceable. Are there any tools out there for "fixing" tar or tar.gz formats?

I am unable to get the Mingw tar to work with compress files. It does not filter through the proper compression utility. However, tar will work if I manually uncompress the file first.
