I'm trying to unarchive an extremely large 7zip file, however I'm getting the error message of "Can not open file "zip file name.7z" as archive. After doing some searching, it appears people have been able to successfully open these types of archives after posting the first and last sections of the hex of the file.

So I'm hoping you could point me in the right direction on how I might be able to recover this data:

File Size - 191GB

2DBB75610 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

The 00 continue for quite a long period up in the archive so I'm guessing it may be completely gone. But any assistance in getting any of the data out will be very appreciated!
