In Unixy environments like Mac and Linux the application can’t always know what the mountpoint of a drive is so it’s not always obvious which root folder to put those index/config files in if it’s a portable drive or network drive. Some mountpoints are standard per each OS, but not everything sticks to the standard.
Iirc they’re indexes for the system wide search feature, Spotlight
Is there a valid reason not to store that [[anywhere else]], ideally in Spotlight’s data?
