I need a tip for a better way of deleting obsolete referenced documents. I have a down rev/old version of a sub-assembly mixed in with the full assembly of a machine I'm working on. I would like to delete this old sub-assembly and all its no longer used components from the main folder. I can do it the long way, i.e. open up the sub assembly, list the referenced components, close it back up and then delete the files on the list or .... Since there are quite a few old components, this can be pretty time consuming. I would think there is a more streamlined way of cleaning up the obsolete parts from the project folder. I tried SW Explorer but, even though it will list the old references, it does not have a command to delete them. Sure would appreciate any suggestions.
