Been searching for a way to execute "Clean Database & Cache"
(AE > Preferences > Media & Disk Cache > Clean Database & Cache) (clearing conform media from the system) by way of ExtendScript.
Over at How to "empty the cache" by a script?
There's a command
app.executeCommand(10200);
for emptying the cache (AE > Preferences > Media & Disk Cache > Empty Disk Cache...) which clears out the playback cache.
Looking for something similar for this feature.
