SETTING PREFERENCES
The option also controls whether a shortcut chosen as the destination location when saving attachments is treated as a regular file, in which case the shortcut will be overwritten by the file being saved, or as a shortcut file, in which case the file being saved overwrites the file location that the shortcut points to. By default, a file being saved to a shortcut location overwrites the file that the shortcut points to.
To attach shortcuts and treat shortcuts as files when saving
1. Choose File - Preferences - User Preferences.
2. Under Additional Options, select "Do not dereference shortcuts in file dialogs."
3. Click OK.
