The unsigned short limit of 65K is an old zip issue. This is why people tar up large numbers of files, then zip just one tar archive.

Thanks for replying. So something like TAR everything and ZIP the single file. Alright, that's one thing I haven't tested yet. I assume this 7zip tool can be imvoked as part of an automated process.

I�ve already tried to gzip every indivual file, tar everything and send the single file. I�ve tried TGZ as well, but both "solutions" are time consuming.

Otherwise I came up with the alternative to split the files into 50k "blocks" (thus flying under the limitation) and send multiple ZIP archives (between 1 and 6 basically in our case) but I actually think the solution is bad.

EDIT: Is it a fair assumption to say that most businesses would opt for a solution involving TAR?
