> I just hope Microsoft can do something like that with current Explorer app

They can start by making explorer startup in less than 5 seconds. Let's face it, Microsoft devs don't care about performance and probably never will.

Explorer is slow because it's extensible. All the thumbnails and extra stuff in the context menu is what slows it down. There's some pathological cases like "opening a folder with an MP3 file in" which puts it into scanning all the files for ID3 tags.

Fpilot is a great example of how it's possible to make something MUCH faster by limiting the feature set.

(also some of the NTFS APIs are horribly slow for extended information)

Why would this parallel background task have any impact on Explorer's startup time or UI responsiveness?

File Pilot supports explorer extensions... There's an actual animation showing it on the website. What do you mean by "limiting the feature set"?

I don't know if Windows Explorer has regressed since Vista, but back then I remember it doing everything I wanted and more, down to viewing and editing MP3 and JPG metadata in some panel, filtering, grouping, smart searches, etc.

What else do you need from it?

I don't know the state now because I've since switched to macOS, which has Finder, an absolute toy in comparison (other than QuickLook and Column View)

> It's good now

Are you able to clarify what it does better now than it did 10, 15, 20 years ago?
