When I try to do a local mapping from TFS, I get the following error,
The working folder --- is already in use by the workspace ---;User on computer ---
Any ideas on how to solve this?
If the referenced workspace is no longer in use, you can delete it with TF.exe.
tf workspace /delete [/collection:TeamProjectCollectionUrl] workspacename[;workspaceowner] [/login:username,[password]]

You can also use a tool like Attrice TFS Sidekicks to find and delete it.
Otherwise, listen to what the error says and map the workspace in a different folder.
