Nemo is the default file manager of the Cinnamon Desktop. You get it in Linux Mint and other distributions with the Cinnamon desktop.
It’s a powerful file manager with plenty of features you might not know. Some tweaks are hidden inside the Nemo settings while some require installing additional extension packages.
I have included commands for installing extensions for Ubuntu and Debian-based distributions.
Note: Please don’t go and install all the extensions. Only use the ones you would use.
1. Enable quick file preview
Nemo Preview is a cool feature that comes in handy if you want to peek into some files on the go. You can access the preview feature for images, audio, video, PDF, etc.
It also allows scrolling the documents in preview mode and adds a floating control with a seek par in audio/video preview.
