vim-dirvish VS rnvimr

It is cool but not unique. vim-dirvish has existed for Vim since a long time.

vin-dirvish fits your requirements.

I use vim-dirvish(you probably want to pair this with vim-enunch), it's a more minimal version of Netrw.

There is the built-in file browser, netrw, but I switched from that to vim-dirvish to lir.nvim to oil.nvim. These are file browsers, not file trees, and my preference for them is probably because I became accustomed to netrw after using it for so long.

vim-dirvish (great NetRW alternative)

file managers or project/directory viewer

vim-dirvish

There's also a minimal alternative if you're interested lir.nvim. Although I still use vim-dirvish because it meets all my needs.

I use dirvish, but netrw is often sufficient

You can ranger inside of Neovim with this plugin rnvimr. Check it out. Neo-tree is another plugin that I like as a file manager. And also mini.files is another option if you prefer a more minimal approach and the ability to manipulate files like you edit a normal Neovim buffer. I'm pretty sure there are other great options out there as well, these are just my personal preferences.

https://github.com/kevinhwang91/rnvimr is pretty good, it opens ranger in a floating terminal and takes care of file renaming and deletion, etc.

Ranger inside Neovim for when I need it

This plugin is unique from the other alternatives such as ranger.vim and rnvimr in that my plugin has no dependencies besides ‘ranger’ and written in 100% lua.

chadtree for dealing with files in the current project & Rnvimr (which basically integrates Ranger) when I want to work with files all over the disk.

Although Ranger is a terminal application, you can use it in neovim via some plugins like rnvimr.

If you don't mind switch to another plugin I highly recommend rnvimr to use ranger, a real-world, feature-complete file amanger perfecrly integrated in nvim.
