I zipped up about 3 gigs into a 2.24 gig zip file. I did it with stuffit deluxe, and I had no problems opening it. Then, I sent the file over the network to my roomate and reformatted/reinstalled OS X Tiger, then d/l'd the file back from my roomate. Now, it won't open! I'm just using the standard OS X BOM ArchiveHelper... it gets like 75% done and says: Unable to unarchive "filename.zip" into "Desktop". (Error 1 - Operation not permitted.) Any ideas? Thanks in advance.
