I use total commander and x-plore.
I would use only TC but sometimes i can't overwrite files, while x-plore can overwrite most of the time. I would not recommend x-plore becouse it has ads (with adaway i don't see) and is not opensource (i think).
I still use ES-Filemanger. The last version before all the BS crap was added onto it and before they sold it to Cheetah. Even until this day, it is the best I have found that has a lot of tools and it that it is free.
