How to Add Favorites in Windows 8.1's File Explorer
If you frequently access a specific location using File Explorer in Windows 8.1, you can add that location to the Favorites section of the navigation pane for easy access. For this exercise, select the Documents folder. (These steps work for folders, not files.)
Select a folder you have created (or any other folder).
On the Home tab, select the Easy Access button.
From the drop-down list, select Add to Favorites.
A shortcut to your selected location appears at the bottom of the Favorites section in the navigation pane.
To remove a shortcut from Favorites, select the Favorites heading, and then select the item you want to remove. Select the Delete button on the Home tab. This action deletes just the shortcut, not the original folder.
The Easy Access button also has an option to Pin to Start, which adds a tile for this location to the Start screen.
