How can I see a folder and a subfolder in the same window?

Solution 1:

Yes I got it.. It's marlin file manager

If you want to install execute following commands in terminal:

sudo add-apt-repository ppa:marlin-devs/marlin-daily
sudo apt-get update
sudo apt-get install marlin

Hope it helps you..

Solution 2:

This is one of the main reasons I always use List View:

It's not always ideal.

Some file managers have a multi-pane option. Nautilus used to but this was stripped back. There has been a bit of a struggle to get it back but I'm not sure how viable that is now.

I use Dolphin these days (I'm also a KDE user so that makes sense for me) which might be an option if you're doing this a lot. List view plus split screen FTW:
