Windows 10 comes with the Maps
app preinstalled. Maps is your guide to everywhere. Find your way with voice navigation and turn-by-turn driving, transit, and walking directions. Search for places to get directions, business info, and reviews. Download maps to use when you’re offline. Tour the world virtually with aerial imagery and 360 degree street-level views. Plus, you get the same experience across all your Windows 10 PCs and phones.
If you would like to search for places and get directions in the Maps app even when you are not connected to the Internet, you should download maps for offline use
Since offline maps can use a large amount of storage space on your hard drive, you can change where you store offline maps at anytime. When you change the storage location of your offline maps, all existing downloaded offline maps will be moved to the drive location you select, and any new offline maps you download
will be saved to the new location.
This tutorial will show you how to change where you store offline maps
for the Maps app in Windows 10
