Extension-Type Associations

With extension-type associations, users of both the Windows 2000 and the Macintosh version of an application can work on the same data file. The extension-type associations provided with Services for Macintosh tell the Finder which MS-DOS file name extensions correspond with which Macintosh file types and file creators. When a file on the server has a file name extension associated with a Macintosh file type and file creator, the Finder displays the appropriate icon for that file when a Macintosh user browses the files available on the server. If a Macintosh user chooses the file, the appropriate application starts and opens the file.

The extension-type associations shown in Table 13.6 are already defined. Others can be added to Services for Macintosh. For a comprehensive list, click the Association tab in the Configure File Server for Macintosh dialog box, in the File Services Management snap-in.

Table 13.6 Extension-Type Associations

You can also add extension-type associations. You can add new associations for an application not listed in the preceding table, or you can add extra associations for any of the listed applications. For example, if your company has a custom of saving Microsoft Word documents with a .wrd file name extension, you can add one of the extensions listed in Table 13.7.

Table 13.7 Additional Extension-Type Associations

When you add a new extension-type association, it affects only files that are subsequently created on the server, not the currently existing files. Moreover, you can associate multiple extensions with a Macintosh file type and creator. However, the reverse is not true. Only one file type and creator can be associated with an extension.

Note

The WKS and WK1 formats allow a single data file to be used by users of Microsoft Excel, Lotus 1-2-3, and Informix Wingz. However, you can set up an extension for only one Macintosh application for this format. For example, if you map the WKS and WK1 extensions to the file type and file creator values for Microsoft Excel for Macintosh and then a Macintosh user double-clicks the file's icon, the file is loaded into Microsoft Excel for Macintosh.
