Right-click the folder and choose Pin to Quick access.
Step by Step
- Open File Explorer.
- Find the folder you want to keep handy.
- Right-click the folder.
- Choose Pin to Quick access.
- The folder should appear in the left navigation area.
If That Doesn't Work
- If the folder is already pinned, the menu may instead offer Unpin from Quick access.
- Network folders can also be pinned, but they must still be reachable when you open them.
