Is it safe to delete this folder? From what I've read, it just holds App Store cache. I'm running really low on disk space, and this folder is massive.
Edit: The filepath is: Macintosh HD/private/var/folders/bw/0tlgj1q56zs3msbssd_w4jv40000gn/C/com.apple.appstore
All the folders inside of it contain a package and a file called preflight.pfpkg.
Edit 2: I took a closer look at the packages inside and it looks like they're all Xcode installers, like every single one of them. I made a Time Machine backup in case something went wrong, but so far it's been smooth sailing.
