Data Recovery software

[tossbag]

Hi everyone, my father in law has an SD card that has lost all the files on it. I have recovered a few with R Studio but there are loads still gone.
Any recommendations on what software to try?
Thanks!

ZAR (Zero Assumption Recovery) is the best I have used.

Not sure what files you are trying to recover, free option for more common files is recuva which is relativly easy to use, go for the deep scan option.
