After playing around a bit - I was able to rename the sub-folders in my projects in Team Foundation Server but it will not let me rename the root project folder. Any ideas why? Below is a screen shot to illustrate the problem.
As you can see I was able to rename the folder under UniversalCheckInApp to UniversalCheckInKiosk but I cannot rename its parent folder as the rename option is disabled when I right click on that folder. Some more information - Dev folder that is the parent of UniversalCheckInApp is not mapped but the UniversalCheckInApp folder is mapped to a local folder. Any assistance would be greatly appreciated.
OK so after playing some more - I was able to figure it out. I had to do a mapping at the Dev folder level. Then the rename option became available for the UniversalCheckInApp folder. It would be really nice if Microsoft would work on a better way of doing this.
