SHK file forked?

I'm copying the an shk file to 800k disk on an older mac. when i try to unshrink i get something about the file being forked. any ideas?

What is contained in the SHK archive? Are you using GShrinkit to unarchive it? Is the 800k disk you've copied the SHK archive formatted as a HFS or ProDOS volume?

Resource forks are supported in System 5 and 6 on the IIGS, just like they are on the Mac.
