Mac OS X makes opening .zip files simple: you double-click them, and the OS quickly unzips them. But one thing has always bugged me: After I unzip it, the original .zip file—for which I no longer have any use—is still there. I’d rather my Mac clean up the zipped versions of files automatically after I expand them, instead of leaving me with one more thing to get rid of.

I used to end up letting a bunch of zip archives pile up in my Downloads folder, sometimes taking up gigabytes of precious disk space. This handy trick helped me to clean up after myself once and for all.
