When you want the files saved in OneDrive for Business to be accessible from your computer without logging in with a web browser, sync the library. This requires you to install the OneDrive for Business app on your computer.
When you install the OneDrive for Business app, you will automatically sync your entire OneDrive for Business library to your computer. You can instead select certain folders to sync while leaving other folders unsynced.
If you’ve synced your OneDrive for Business with your PC, you can easily access files while not online. Double-click the OneDrive for Business icon in the system tray to view and open the files. Once an internet connection is restored, the files will sync to the online location.
If the location of your OneDrive for Business folder on your computer is tough to remember, or if you just want to get to it quickly, you can jump right there using the OneDrive for Business app.
Click the OneDrive for Business icon in the system tray.
A small window opens, showing recently added and modified files.
Click the More button to access OneDrive settings, pause syncing, or manage your storage.
Click Open folder.
OneDrive for Business opens in File Explorer. All the files from folders you have synced appear here.
The green check mark means the file is synced and exactly the same as in OneDrive for Business.
