What is the purpose of /Users/Shared/adi? While backing up my macOS using Time Machine I came across the following folder: /Users/Shared/adi.

What is the purpose of that folder? Can this entry be safely removed?



Btw. There is already some blog post about it, but it really doesn't clear it up.
Apparently, these files somehow belong to the Mac App Store and the iBooks app. "adi" might be referencing "Apple Distribution International". Removal from the excluded Time Machine items is not recommended, as this behaviour does seem to be expected from all macOS installs >= 10.8 Mountain Lion.
