I'm used to Linux, and I always say ctrl+alt+t to open terminal operation files. Sometimes I want to look at the file. The terminal type of file display is too simple to see the thumbnails of files such as images and videos.
So the tool recommended today is nautilus
Enter directly on the command line:
nautilus
The folder window of the root directory will open directly.
If you want to open the folder window of the current directory, you can:
nautilus .
Directly address needs, clean and hygienic.
