duplicate directory files showing up in .zip

[multiplier]

I'm trying to release a WordPress theme on my site which I've developed on the Mac. When I sent it to my friend with a PC, he unzipped it and noticed it generated empty files based on the names of the subdirectories (see attached image). Also when you first open the .zip, there's an empty folder called __MACOSX. Any idea how to keep the whole package a little more clean?

Those are standard Mac metadata files that will be created on any filesystem that doesn't have native support for said metadata and/or Mac file resource forks (which basically means FAT-formatted disks). The same would be true of .DS_Store files, which are view metadata for folders.

A quick Google search turns up this:

...which may help.

Thanks a lot Makosuke. I think my Googling failed because I wasn't quite sure how to phrase my question and wasn't sure what the metadata/resource fork stuff was called. Price of being a newb 🙂
