When a user or app uses a PD cloud file it downloads it and the cloud file stub changes size from something tiny to the full size of the file.

The size of the desktop PD directory could become very large and the size increase could be very sudden. At the moment to shrink it, you have to manually do a Free up space on individual files or directories from Windows File Explorer.

Suggestion:
Have a scheduler to automatically run Free up space to clean up after user downloads at least once a day or week, perhaps maybe a user defined schedule.
