Suppose I have a Linux server that's running a Node app that stores data in the file system.

I don't want to go to the trouble of running a full desktop shell on the server, rather I'd just like a way to browse the filesystem structure in a tree format, through a web browser.

So I'd install a piece of software on the server that provides very basic file browsing capabilities. Just to help me debug stuff.

Does such a thing exist?

PS: Right now I'm using Dropbox for this, but it's way overkill. I don't really need to have the files sync'd -- I just need to be able to see what's there.

PPS: We got a good answer.
