It is very handy to have some extra directories added to the sidebar in the Ubuntu file manager (Nautilus) to allow quick navigation, especially if one has rather complex file structures on your computer.
- First, open the file manager
- Select the directory you would like to add to the sidebar and enter that directory (!)
- Once inside the directory, go to the Ubuntu title bar and select Bookmarks/Add Bookmark (Note that if you are not inside the directory, it will not work!)
- The directory will appear in the sidebar of the file manager, granting fast access from now on to the files within that directory.
