The Open tab on the File menu shows a list of files you’ve recently opened, and it includes links to places where you commonly store files.
Double-click Computer to get to local files, including removable flash drives. You can also select one of the locations your accounts let you get to, sign in if necessary, and then open the file you want. To add a new location, click Add a Place.
The Recent list shows the files that you opened recently from any of your devices. If this list gets unwieldy, you can delete files from it. Just right-click the file name and then pick Remove from list. You can make other changes to the Recent list. To learn more, see Customize the list of recently used files. If you don’t use the list of Recent files, and you’d rather jump straight into browsing folders, use Ctrl+F12 to open the Open dialog box directly.
Tip: If you want to bypass File > Open and always use the Open dialog box, do this: Select File > Options > Save, and then select the Don’t show the Backstage when opening or saving files check box. Then, close and reopen any open Office applications.
Recover unsaved documents
You might also see the Recover Unsaved Documents button if you've experienced a situation like accidentally closing a file without saving it or a power outage while you were working. Sometimes there might be a mismatch between the AutoRecover location that's set in File > Options > Save and the path where this button goes. If that happens, do this:
Go to File > Options > Save > AutoRecover file location to copy the folder path where AutoRecover puts your unsaved files.
Click File > Open > Recover Unsaved Documents.
In the Open dialog box, delete the path that's shown and paste the path you copied in Step 1. Then, click the Go to arrow.
Open the folder for the file you want.
Open the file. It has "Unsaved" in the title and a .asd file extension.
Save the recovered file with a new name. You can overwrite the original file if you don't want to have two copies.
Tip: To help prevent the mismatch in the future, update the File > Options > Save > AutoRecover file location to the "UnsavedFiles" path that the Recover Unsaved Documents button takes you to (the path will be something like: C:\Users\<username>\AppData\Local\Microsoft\Office\UnsavedFiles)
