Very big pkg-files in private-folder
I'm using macOS Catalina 10.15.1. My hard-drive is 121 GB in total and 35 GB of this is Others when I'm checking the disk-space. I'm running OmniDiskSweeper and there are two big files in the Private folder (private/var/folders/..../com.apple.appstore that are .pkg-files (one 7.8 GB and one 4.2 GB). I know that I should not mess with the private-folder but to me this looks like installer files. Any way to check if these are part of a failed download from Appstore or if there is any safe way to get rid of them to free up diskspace?
