I am running extremely low on disk space and trying to clean up my Mac. Disk Inventory X shows me having over 20gb of space in .pkg (installer package) files in /private/var/folders/pj/_(random)_/C/com.apple.appstore/*

I am wondering if these are safe to delete (they are in /private after all)? However I really don't want to give up 20 gigabytes to installer files.

Also, is there any built-in way to delete them (meaning through appstore menu or something, not via finder)?

That is the Download folder for App Store; where it saves apps as it downloads them.

It should be perfectly safe to delete them.

However, I have to say that it is a little strange that the files aren't being deleted automatically, either when you close App Store or when you restart - that is what I would expect. I haven't come across a case where they build up over time.

    Thanks for the information. Neither restarting the computer nor closing the App Store cleans up those files. Deleting the files seems to have no impact on my programs, but I did keep the receipt files behind in case they have something to do with my licensing. – Ryan Knuesel Nov 13 '12 at 17:26
  • I had this exact problem, and all leftover files seemed to be identically named XCode installers. It represented around 30GB of data. – Kenn Sebesta Jun 24 '20 at 11:45
