I think I need a little guidance with this if anyone could help ? 
When I first used this I  thought the behaviour would be, to move a folder acquired from GetFolderInfo,  into the the path I specified as the first parameter, retaining the moved folders EntryID. Same as would happen with a move Workflow activity. 
This didn't happen though. It tries to overwrite the last folder in the path parameter I provide. I then added the name of the folder I'm moving to the end of the path. I then get "EntryID not found".
The description in the documentation is 'Moves the represented entry to the specified path'. What am I doing wrong ? Missing an Option perhaps ?
