I am using TFS from VS2013. I have created a workarea and then I assign a local path in my computer to start getting last versions of some branches. I sometimes want to change local path of a branch (already mapped to a local folder) to point to another different local path from the same workarea or even to another local path of another different workarea. So I go into local path and I remove the content but Visual Studio already is pointing to that path and in the source control explorer path appears marked as white color instead of indicating it as not assinged and not allowed me to change it. How can I do this?
Also there is another case in which I am interesting in: If I has a branch already assigned to a local path within a workarea and I want to remove this and keep it again as unassigned how can I do it?
