Assuming you would like a guide on how to add quick access to file explorer in Windows 10:
- Right-click on an empty area on the taskbar and select “Taskbar Settings”.
- On the taskbar settings page, scroll down and click on “Select which icons appear on the taskbar” under Notification Area.
- Toggle on “File Explorer” and click/tap on OK. (see screenshot below)
- File Explorer will now show up as an icon in the far left side of your taskbar next to the Start button whenever it is open.
