Disk Cache's for previous versions over 100gb due to renamed computer.

When Mac OS connects to a WiFi network, it will prevent conflict by renaming the machine to the current name + a number.

After Effects stores the cache data by the machine name. This means if a machine is renamed multiple times, AE will not detect the cache going over 100GB as it creates a new one. 

This has led to 1.3TB of Caches being stored for me and AE unable to detect the presence of these files and purge them. Renaming the machine back doesn't help and it is still unable to detect the older files.

It does not read the Cache location folder size - it assumes it's database is working properly and doesn't touch any other files.

Solution is to manually trash previous versions caches.
