  Choose the Re-create... menu item to re-create a
  collection.

  If you change a test, a variable definition, or
  something else in the library since you created the
  collection originally, the re-created collection
  reflects the changes.

  Digital Test Manager deletes the old collection and
  all its related files except the benchmark file, then
  creates a new collection with the latest versions of
  each required file.
