Files ignored

I just ran Recuva on a SSD. It reports "Found 0 file(s) (253 ignored)." Why does it ignore the files I am trying to recover? Thanks!

It doesn't. Ignored files are non-deleted, zero length, and system files, which you would not usually want to 'recover'. It is an unusually low number of files though.

Deleted file recovery on an SSD is not normally possible, due to the SSD controller zeroising file data on deletion.
