I needed to find all of the files that I had changed and checked in to support a specific change I implemented. There were multiple files in multiple directories that were checked in as one atomic operation (changeset). The best way I could find in VSS was to select the root project ($/), right-click on it and select "Show History". Be sure to select the "Recursive" and "Include file histories" options before pressing Ok. You can also specify a date range (if you don't, be prepared to wait!).
It would have been nice to filter a date range here, or show the changeset and let me drill down to the files that make up that changeset, but maybe I'm just too used to SVN. But at least I could identify the changed files and go to each and every one to find out what I had to do with them.
