Is there a way to compare and show only files which has increased filesize?

Hello.. I wondered if someone knows a way to get DO to compare two drives (one ordinary drive, and one mounted backup of it behaving just as a drive), showing the files which has increased in size, or files which doesn't exist on the other drive?

I don't know if find can compare filesize for a file with the identical file/path on another drive and return a result if it matches.

I've tried using Synchronize for this, but it gets too hard to read.

I use dual view.

If you turn on the 'Hide unaffected files' option in Synchronize it will only show you what's changed.

This works, at least for checking for any differences at all.
At least it limits the list a bit.
Thank you.
