I was posting somewhat complex zip files containing php code. Folders within folders.
PC users complained that they opened them and found the folder structure within the archive that should look like parent/child/subchild showing up as parent:child:subchild. So instead of a hierarchical structure they were just seeing many files at the top level with long, confusing filenames.
The Mac does not use / internally it uses a :, I understood what was going on but PC users were baffled and complaining. To get around the problem I starting zipping on my Linux webservers using ssh, upload the folder then zip it there.
Mikuro, do you know of a way which would solve this problem locally?
