> file manager available on any platform as good as Windows file explorer.

How come? I can't think of a single redeeming feature of windows file explorer that I need (or use).

Heck, it effectively doesn't have text search (grep -R) and b/c it's so bad there is the "window search" service that even worse. It has the absolutely worst imaginable zip file (erm folder) reader as a side bonus. Security file permissions management is just horrid (along with the fact some of them are coupled with registry paths)

I don't recall seeing a correct file system operation time estimation.

Edit - since explorer.exe is both the shell and the file manager, and the former craps itself often enough (task manager or taskkill /im explorer.exe), it's another negative point.
