Use the File Explorer! It is located in the Tabs on the Right side of your Graphics window. Just add a Shortcut to the ‘Samples’ folder in your SolidWorks install directory, click the ‘folder’ icon in the Tabs to the Right in your SolidWorks Interface and open the Samples Folder. There you will see all of your files without having to click FILE | OPEN every time you need to get to them.
Either Double Click the files to open them in SolidWorks, or you can Drag and Drop them onto the toolbars to open them OR Drag Part or Assembly files directly into Assemblies to insert the Component or Sub Assembly.
Unlike the Design Library, the File Explorer gives the user access to not only SolidWorks files, but any file that resides in the folders.
