Hey!

Just in case you didn't know (and to avoid probably 30 minutes of download time for the next person), you can safely delete the library and temp files from the Unity project files.

The library will be rebuilt the next time the project is launched, and temp are temporary files that aren't that important.

Good luck!

You need only three folders to be zipped: Assets, Packages and Project settings. Unity will add everything else by itself. It will be only few megabytes.
