If you previously synced to your VPO document library, you can stop syncing these folders at any time. When you stop syncing a folder, you disconnect the folder on your computer from the library on the server. You can always sync the library to your computer again.
Note:
You can also pause syncing. This allows you to temporarily stop syncing a folder without disconnecting it from the library on the server.
Instructions Update 4/2/2020:
Click on the blue cloud icon from your task manager toolbar (bottom right of screen). Select 'More' and then 'Settings'. Choose the 'Account' tab. This will bring up a dialog box with a list of all the synced folders.
