I use MiXplorer because of its features although it is slow because it doesnt cache or index the files
Been using FX for years on Android. Does what I need.
For Android, Amaze is the best open source file explorer I have used. Back when I didn’t care about open source, I liked Solid Explorer.
Mixplorer
Solid Explorer 2 for Android. Been using the it for many years.
I use X-Plore. it has two panes that you can swipe between and it got an archive manager and an app manager. also root.
