If the file cannot be browsed from My Recent Documents, check if the actual file exists in the target with the steps below:

1. Right-click on a given file name in My Recent Documents and click Properties.
2. Click the Shortcut tab and check the target of the shortcut.
3. Copy the target of the file and check if the actual file exists.

Note: If the file has been deleted or moved, it cannot be browsed as My Recent Documents shows the shortcuts of actual files. If the file is saved in a media such as a floppy disk, the file cannot be browsed from My Recent Documents unless the media is inserted.
