Most frequently I use it as an interactive cd. Docs on how

Saves me a whole lot of ls and cd or tabbing through completions.

I mainly use it inside neovim actually, in place of the built in file manager or a file tree. Also use it if I want to quickly see the image files in a directory (it shows the images in the terminal), or rename a bunch of files. And then rarely for other file related activities as it makes exploring a directory very smooth

It hooks into nearly every base utility I can't live without (fzf, jq, helix, ripgrep). If you're on windows im not sure you're going to get a ton unless you live in WSL.

You can pick the editor it'll open by default, which should be configurable with comparable syntax highlighting. Vi can pretty much look like whatever. I think it'll default to vscode on windows.

Im not sure what you'd use it for but manage files, but I would have poked it and probably moved along while I was still on windows.

Edit: the other benefit you might not see has a lot to do with support of mime types.

The xdg open protocol will open whatever app is assigned to handle type locally. Which is probably why it defaults to editor.
