Because Logic projects get mangled if you upload them to Google Drive (because a Logic project is a folder in disguise), and because you don't want to upload a single zip file with ALL your Logic projects in...
This in and AppleScript which you can drop a folderful of Logic projects in, and each respective Logic project gets zipped into its own zip file. This make collaborating with Logic using Google Drive much easier, so your band mates can download just the song they want to work on.
Open this script with Script Editor.app and save it as an Application, then drop your folder (that contains multiple projects in it) and your zips will appear your Desktop. Note: It makes uploading a bit easier too, cos it's multiple files rather one big whopper.
