Project <Project> does not exist

This error has the following cause and solution:

• You are attempting to move a project to a parent project that does not exist.

  Check the path of the parent project and try again. If you are unsure of VSS project syntax, try selecting the parent from the project list in VSS Explorer, and then note the project path displayed above the file list.

Note   To move a file or subproject to a new parent, you must have already created the new parent project. Use the Create Project command to create a new project.
