Oops, screwed up a copy with append, how to fix?

[SkyHog]

I was trying to copy some files from one location to another today, and I screwed up, the files are now appended into one file. Is there a way to fix this and split it back into files?

I typed:
copy s*.* z;

Instead of
copy s*.* z:

so now I have one file named z that holds the contents of all the files. I'd like to split them if possible.

yeah...
rm z

you still have your original files, because copy copies, not moves which is a copy and delete (well, sorta ... it just fiddles with the file header bits...)
