I have a file from TREC(Text REtrieval Conference) whose extension is .0z .1z etc etc. I tried every method I can do, but still failed. Could someone do me a favour please?

There are some evidence that might helpful.

  1. In terminal, I used “file” command then it shows “fr940104.1z: compress’d data 16 bits”.

  2. I also check the properties of the file under GUI, which shows UNIX-compressed file(application/x-compress).

    and are stored in chunks of about 1 megabyte each

    indicates that you need to recombine the chunks before decompressing. Hopefully the filenames can help you with that (“chunk001.z”, “chunk002.z”, ?). Assuming that you can figure out the order, use cat to combine them into one file. Then use Unix uncompress. Or pipe directly from cat to uncompress.
