>Probably because Windows Explorer is great file manager.

Having it pointed out like that, you're right. I think my 'big' complaints about Windows Explorer have just been the lack of tabs, which I think are being/have been added in Win11) and the multiple-windows-single-process model, which hasn't been as much of an issue lately with explorer being a lot more stable.

Otherwise explorer is a very smooth experience. I just treated it as bad because of frustrations with Windows in general.
