Product: Adobe Premier
Q. Where does Adobe Premier keep its cached files?
A. By default On Window it uses:
C:\Users\[username]\AppData\Roaming\Adobe\Common\Media Cache Files
You can change this in Premier from:
Edit > Preferences > Media > Location
There is also a "Clean" button there.
I have found that button doesn't delete everything.
So you can exit Premier (and other Adobe programs) and delete
all files in that folder using Windows File Explorer.
