What sense does it make that Photorec offers recovery from non-free disk space? These files don't have to be recovered because they are visible anyway!?
Can somebody explain that?
Thx

There is no such option.

Please read carefully what your options are:

In case of desaster (destroyed metadata) you would like to search the whole partition. It does not matter if some clusters/sectors were formerly belonging to a file system structure as that structure is either destroyed or unusable.

ok, but what happens when you search the whole disk of a healthy disk with working metadata and file system? photorec should find nothing, right?

Photorec is not necessary when nothing is broken.

you don't say!
but the question was, does it find (fractions) of deleted files on that (full, non-empty) part of the disk or will it show all files or find nothing?

Please simply try it out. I can only guess and your question is not related to the purpose of this program.
