When I compress files with the built in zip compressor in Mac OSX, it results in an extra folder titled \"__MACOSX\" created in the extracted zip.
Can I adjust my se
You can't.
But what you can do is delete those unwanted folders after zipping. Command line zip takes different arguments where one, the -d, is for deleting contents based on a regex. So you can use it like this:
zip
-d
zip -d filename.zip __MACOSX/\*
