In Visual Source Safe 6.0, you could "reset" a working folder by setting it to a blank string. This meant that the working folder would be determined by the working folder of the parent.
How do I do this in Visual Source Safe 2005?
This can't be done in the normal VSS 2005 "Set Working Folder" dialog.
However, if you hold the shift key while invoking the "Set Working Folder" dialog, it shows the old VSS 6.0 dialog. Here you can reset the working folder by deleting the string and pressing OK.
