I've got a .7z file with a bunch of our old music in it and I can't get to it. It's about 2 GB (2,141,576,224 bytes it says) with 1,000-some files. On extract it says about 700 of them are broken. In the 7zip file manager it's telling me how big these broken files are, so I believe the data is still there. Any help is appreciated, I'm sure this isn't much to go on but I can get more information if I know what I'm looking for.

Thanks in advance.
