File manager APP with Root access disappeared after factory reset

I did a factory reset and after recovering my file manager app disappeared. This is already weird on itself.
I cannot find it either in the phone nor in my play store. I tried to search it in google play, but I wasn’t successful. There are dozens and I cannot find it by the pictures…
It was one recommended somewhere in the forum, but I cannot find the topic. I thought it might be good, if we can list apps with root access, which are working for you.

It might have been Amaze or TotalCommander.
