This issue is related to the dropbox Desktop application/program. Using the windows File Exploroer to browse my Dropbox folder I attempt to change folder names I would get an error "The action can't be completed because the folder or a file in it is open in another program, Close the folder or file and try again". This issue is the same for all Droxbox folders and only way to change the folder name is to logon to Dropbox on Google chrome and rename folders from there.
Is there any way to correct this issue so I can go back to use Windows File Explorer to rename folders?
