I front end several of my file device class pool with a disk device pool which 
will migrate to the file device pool and control the number of filling volumes. 
 Volume that are in filling status will not reclaim, but you can manually move 
the data.

FILE allows deduplication; DISK doesn't.

My impression after some experimenting is that FILE wasn't meant to replace
DISK; it was solely meant to replace tape device classes. We didn't need
to, so those experiments quietly ended.
