Macintosh files stay linked to the applications that created them; with Windows, this isn't always the case. Double-clicking a Macintosh document icon automatically opens the application that created it-no matter where the application resides on your hard disk (or connected server) and no matter what the file is called. With Windows 95, it's not that simple. The association between applications and files is still governed by pathnames and the three-character filename extension. That means that double-clicking a document sometimes opens the application that created it and sometimes doesn't. For example, when you move an application on a PC running Windows 95 to a different directory-or even rename the directory it's in-and then try to open a document created by that application, you will usually receive an error message stating that Windows cannot find the application. Here's an example of what's required for the simple task of moving an application and a file that the application created, then opening that file.
