If you have used clearcase before, then this question is for you. How do you determine all the files and their corresponding checkins?, given a snapshot view.
Use cleartool find: it can list all the (checked-in) version ever created from within a path of your view.
See also those additional examples.
If your question is about finding checked-out files, then
See "how to find out all the checked out files in a branch" and "Recursive checkin using Clearcase" (for dynamic and snapshot views)
