Can't remove workspace from TFS - tfs

Question

I want to add my project from Visual Studio 2012 to my TFS server, but it says the path is already mapped for workspace pc;administrator (this is a local workspace).
I have tried the command tool tf but it says that there are no workspaces, so I can't delete the workspace that is conflicting.
I'm running Windows 8 with Visual Studio 2012. TFS is on a windows server 2012.

Answer 1

The problem is that the current project location, the folder on your physical machine, is mapped to a different TFS server. To add it to source control you need to move it to a physical location not associated with a TFS server.
Edit
To remove the offending workspace:
1) Use the "Team" menu to connect to the TFS Server that you do NOT want to be mapped to
2) Use ctrl+q --> workspaces to access the workspaces menu
3) Remove the workspace
4) Change to the TFS Server you WANT to be mapped to using the "Team" menu again
5) ctrl+q --> workspaces
6) Add a new workspace

Answer 2

Try any of these steps out. Some of them may not be applicable to you.

Answer 3

if you use Visual studio 2012 go
C:\Users{UserName}\AppData\Local\Microsoft\Team Foundation\4.0\Cache
or if it is Visual studio 2013 go
C:\Users{UserName}\AppData\Local\Microsoft\Team Foundation\5.0\Cache
Remove all things under it.

Answer 4

Simplest way to do this is to go to your AppData and delete the TFS cache (depending on the version 3.0 or 4.0)
C:\Users{UserName}\AppData\Local\Microsoft\Team Foundation\3.0\Cache
or
C:\Users{UserName}\AppData\Local\Microsoft\Team Foundation\4.0\Cache

First we will check the list of workspaces from VS 2015 Developer command prompt,
Ex - tf workspaces /owner:*
Now we will get the xml format from VS 2017 Developer command prompt which will have ‘owner id’ for the particular workspace,
Example 1 - tf.exe workspaces /owner:* /computer:ComputerName
/collection:https://YOUR-TFS-URL.visualstudio.com /format:xml
We can now delete the workspace for the particular user,
Example 1- Tf workspace /delete ComputerName;email#email.com
/server:"https://URL.visualstudio.com"
OR
Example 2 - Tf workspace /delete ComputerName;1e178c77-bb8b-6f05-bf99
/server:https://URL.visualstudio.com
(Where 1e178c77-bb8b-6f05-bf99 is ID of the workspace which you get from Step 2 XML
format)
Again we will check the list of workspaces from VS 2015 Developer command prompt,
Ex - tf workspaces /owner:*

Answer 6

Well I couldnt find my troublesome workspace, which prompted me to copy the local code folder into another name and I created a new workspace mapping that folder.
Next up I added the new solution to the TFS via VS 2012 using Add Source Control.
