A manager where I once worked demanded that we continue to use (the unpaid for shareware version of) WinZip on one computer that was dedicated to sending data off to clients. After WinZip added the 1 second wait for every file ever processed, he implemented a 'wait and come back rule'.
The count reached over 3000 at one point!
I would just use 7-zip or zip it in Cygwin. But it became so that when I wasn't around clients would have to wait an extra hour to get their files. He sometimes would just sit there and wait for the count to complete. A single license was maybe $25 at the time?
