/me shakes head.
EDIT:
Checked the files; they will never join, as they are.
Each and everyone should be named the same way, save for the final number - eg. wcs.avi.0, wcs.avi.1, wcs.avi.2, etc.
You named each part in a different way: wcs pt1.avi.1, wcs pt2.avi.2 and so on.
The archived is actually working: I simply had to rename all the splits, so Hacha could recognize them.
Just be careful not to rename the files *after* hacha split them.
Reg's.
