Making files available offline

Our company has many jobs running at the same time.  Some of the files are 30+ gb large so it is to our benefit to make them available offline.  The jobs themselves may take a few years to complete.  Some people are finding their disk space is getting very low due to the amount of files they have made available offline.  Is there a way to list all the files that user has made available offline so that they can free up disk space?
