In my Video Pro X directory, I have two subdirectories, "ShopManager_Video_Pro_X12" and "ShopManager_Video_Pro_X13". Are these files and directories necessary, or can they be deleted?
The folders are part of the Store system and should not be deleted.
However the FileCache folder may contain many preview images which can be deleted - they may reappear over time as the Store rebuilds the preview image cache.
