Tool or function to clean-up/remove orphaned member part files. For example I have a project with about 3000 part files. I know I'm using only a fraction of these parts in the current design. These orphaned parts slow down other processes such as the up-load and down-load of the project to and from the server. Also, creates a burden to the server backup, while having little or no benefit once the design has been complete. I cannot just delete all of the member files and rebuild the model because any drawings that were already started or completed will be compromised.
