Solid Explorer. Why? Because I bought it ages ago and if still works fine. Even a decade later, it still gets regular updates, which shows that the dev cares about the app.

More importantly, I like that it jumps straight into my filesystem without any nonsensical abstract views, and I like that it doesn’t come with any bloat (no junk cleaner or RAM booster crap), unlike other file managers. So even after all these years and all these updates, the app remains true to its purpose and hasn’t sold out or gone down the enshittification path, which is a refreshing change compared to what we’ve been seeing with other apps.
