Microsoft made a strange change in Windows 8.1 -- Libraries, a very useful feature, is missing from the File Explorer's sidebar. Here's how to bring it back.
Libraries are still built into Windows, but they're not visible in that sidebar. To bring them back:
- Open File Explorer and expand the View tab.
- Go to Options > Folder Options on the right side of the ribbon.
- Go to the General tab and check the "Show Libraries" checkbox at the bottom of the window. Click OK.
With that change, Libraries will appear just as they did in Windows 7 and 8. The only other difference is that Libraries no longer include public folders. This is a curious change, but may not affect you. Hit the link below to read more about the new change.
