1 Get tagging
Tags are a brilliant way to organize and access files. To create tags for flagging files and folders in Finder, go to Finder > Preferences > Tags. You can use multiple tags, so for example you might apply Work and a project name.
2 Sort your Sidebar
Finder’s Sidebar is one of our most–used Mac features, and if you go to Finder > Preferences > Sidebar you can choose what it should and shouldn’t display.
