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

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.

  1. Restored Library, Thanks BUT when I try to open any folder in any of the libraries I get a message “This file does not have a program associated with it for performing this action. Please install a program, create as association in Default Programs”.

    what do I do now?
