Delete files permanently in TFS
In TFS Source control you can not delete files permanently. Its just a temporary delete. Deleted folder/files can still be viewed from Team explorer through option called “show deleted items in source control explorer” from Tools > Options > Source Control > Visual Studio Team Foundation Server and then can be “UnDeleted” if required.
So, what if you want a permanent delete with NO recovery. This can be done using team foundation command line interface. Following is the syntax for the same.
tf destroy <path for TFS Item to be deleted> collection:<TFS Collection Name>
