When you save a file, you’ll quickly see places available for the account you're signed in to. This way, your Office files are at your fingertips wherever you go, no matter where they're stored.
To save a file to your computer, click Computer, and then click the folder you want to save the file to or click Browse to use the Open dialog box to find a location. Or, click one of the locations your accounts let you get to, sign in if necessary, and then save the file.
Note: The setting in File > Options > Save > Default local file location is only the default for local files on your computer. No other locations have a default setting. You'll need to choose a place each time you do Save As.
To add a new location, click Add a Place. Saving to cloud locations other than SharePoint and OneDrive isn't available in the desktop version of Office programs. However, you can use Office Online and Office apps on iOS devices to edit files in cloud locations like Box and Dropbox (but not Google Drive or iCloud).
If you're used to using the Save As dialog box from earlier versions of Office, you can go back to using that. Click File > Options > Save, and then check the Don’t show the Backstage when opening or saving files box. The setting applies to all your Office programs. If you want to use the Save As dialog box without making a setting across Office programs, just press F12 instead of Ctrl+S when you save a file.
Change how many recent folders you see by clicking File > Options > Advanced. Under Display set the number you want to see in the Show this number of unpinned Recent Folders box. If there's a folder you always want to be shown in the Recent Folders list, hover your mouse over it in the list, right-click, and then select Pin to list.
If you want to open a file from, or save a file to, the root of your Windows drive (i.e. C:\), you first must run your Office app as an administrator.
