I just tried this all different ways of zipping and uploading and can't get it to work right. Does anyone else have trouble with the Mac built in "Create Archive" feature to make a zip file? Whenever I zip certain files they can't be unzipped. I don't know why. I'm going to go back to using StuffIt.
On my old OS 9 systems I always get a "Unknown ZIP header" or something similar when I encounter one of these newer ZIP files, and when I tried downloading Silverwind's QoM, the resource and data forks of each file were split as "filename.mov" and "._filename.mov" files.
Under OS X (10.3) I can usually open stuff just fine, although I haven't encountered enough different kinds of zip compression methods yet to judge whether .zip files work consistently...
The only times I have encountered problems with StuffIt were when the files were in .sitx format...though that's probably because I choose to use an older StuffIt so that I can produce "legacy" .sit archives for wider compatibility.
