You’d get even more savings using something like bees because it does block level deduplication.

What bees does is build a hash table of every block on your ssd, and compares them. If it finds any matches, it will delete one and just place a pointer to the other where the deleted one was, the pointer being much smaller than the duplicate data block.

Functionally, any installed games with shared assets get space savings. It’s particularly helpful on with Steam games because of all the proton prefixes. Lots of opportunities for finding duplicate data blocks.

If you use snapshots, it can save even more.
