  • What are file creators
    While file types and creators are supported in Mac OS X, not all files have them, and no OS X-native applications create files with file types and creator codes. Instead, Mac OS X relies heavily on file extensions as a way to identify a file type (e.g., .txt, .jpg, .tiff). Further, Mac OS X allows you to choose which application you would like to use to open any specific file or group of files. Setting this preference leaves the type and creator codes of a file, if present, unchanged.
    If you want to determine or change the type or creator of a file, there are a number of utilities that you can use. Here are a few examples:

    Mac OS X

    Super Get Info (shareware, $20): Meant as an alternative to the Mac OS X Finder's Get Info command, Super Get Info allows you to view and change the type and creator codes of files, among other settings. This software is available for download from: http://www.barebones.com/products/super/index.shtml
    FileInfo (freeware): FileInfo allows you to change the file type and creator codes of a file, as well as a few other parameters. You can download it from: http://www.panix.com/~shopsinm/
