The purpose of the cleanup operation is to refresh the server and/or the workstation with the most current version of the file on the network. The way in which you checked out a file, i.e. permanently or non-permanently, will determine how the file should be cleaned up.
If you have checked out files non-permanently, these files will be copied back to the server and removed from your local workstations. Files checked out for review (copied out) will be simply removed from the workstation.
Files checked out permanently will be updated on the server, with the files remaining on your workstation. For files that have been copied out to your workstation permanently, the system will check if a more recent version of the file has been posted back to the server. If so, your local copy of the file will be updated with the current version from the server.

After you have selected the Cleanup option, you will see a listing of files checked out to your workstation. You have various options for listing the checked out files:
All files checked out by any user
Files checked out only by yourself
Files checked out only by yourself from your
current project
Files checked out only by yourself more than one
week ago
Files checked out only by yourself within the last week
You initiate the process by clicking on the Clean Up button.
