Fix Error “Documents.library-Ms Is No Longer Working” In Windows 7

© Ramesh Srinivasan | Windows 7 | 30th October 2009

When you double-click a library to view the contents, the following error may occur.

"<libraryname>.library-ms" is no longer working.

For example, the following error may occur when opening Documents library

"Documents.library-ms" is no longer working.
This library can be safely deleted from your computer. Folders that have been included will not be affected.

Similarly when opening the Music, Pictures or Videos library

"Music.library-ms" is no longer working.
"Pictures.library-ms" is no longer working.
"Videos.library-ms" is no longer working.

To fix this problem, open Windows Explorer, right-click on the corresponding library and choose Delete. Click Yes when asked for confirmation.

Note: Deleting a library does not delete the contents of the included folders. However, you may need to re-add or include your folders manually, if needed.

Then, in the navigation pane of Windows Explorer, right-click Libraries and click Restore default libraries.

This recreates the library that was deleted earlier. This option only restores the default libraries.

    Thanks. I was getting fed up and saw this help. The windows 7 error is now fixed, although I do not know why I stopped working in the 1st place – ant Ideas?

    I rate this help 10/10

    I too had a migraine over the .library-ms, searching for days and no fix.
    THIS WORKS: Get a Registry editor and open up HKEY_CLASSES_ROOT scroll to .library-ms and edit the top entry to “LibraryFolder” from “Not Set” or what ever it says. I had to look on a working copy of Windoze7 to glean this and viola!
