Linux says tar file doesn't exist

I'm REALLY new to Linux, so just bear with me... I downloaded a .tar.bz2 file, and I am trying to unpack it. However, each time I attempt to unpack the tarball using tar zxvf Linux says "Cannot open: No such file or directory." I've tried typing the file name in a bunch of different ways and I've tried unzipping the file. I don't know if I'm using the wrong code, or what, but I've been trying to use this file for an hour, and can't seem to unpack it. Thanks for your help...

Edit: Here is a screenshot:

here is one of ls directories

The issue is that a bz2 file is not a "gzip" file - which us what your extract command expects.

Im not near my computer to double check, but im fairly sure you need the -j flag rather then -z to decompress this with tar - try

  tar -jxvf repy-*.tar.bz2
