The Recycle Bin folder stores all of the deleted PDFs and PDFs filed with "Save With". Generally speaking they can be safely deleted. Having said that, as a standard we setup roaming profiles for all clients, but we also redirect all of the main folders within the profile to a file share. ie: AppData, Documents, Desktop, etc..
We also usually setup a logoff script through group policy to clean up the folders. Just make sure you configure the group policy against the user account OU and to run under the current user context. For example the script would contain:
DEL %APPDATA%\PDF Manager\RecycleBin\*.* /Q
I hope that helps.
