I have a strange file without a file extension that's supposedly an archive of the contents of a git repository. According to
file (1), it's an "X1 archive":
$ file my_git_repo my_git_repo: X1 archive data
However, I can't figure out any way to extract or view the contents of this file. I've tried:
But none of these tools recognize my file. I've also tried looking on Wikipedia and the Arch Wiki for help, but neither of these pages mention "X1". I also tried Googling variations of "X1 archive" or "extract X1 file", but mainly I got results for products or services named "X1", and nothing that seemed related to a file format called "X1". Finally, I tried taking a look at the file with tools like
strings, and the file does contain filenames of the files I expect to be in my git repository as well as snippets from files within that repository, so I don't think this file is just random data or anything like that.
What kind of file do I have and how can I view its contents?
