If you want to move MicroGrade class files from one platform to another, we recommend that you create file names that both platforms can read. You will find that this applies when you move files from the Macintosh to a Windows system. We recommend adhering to the following guidelines:

1. File names can contain up to eight characters.
2. File names should contain letters and numbers only.
3. Spaces, punctuation marks or special characters should not be used.
4. Do not delete file extensions generated by MicroGrade. For example, the Windows version of MicroGrade uses the extension .cls to identify class files.

NOTE: If you are going to view a Macintosh class file using the Windows version of MicroGrade, when the Windows version of MicroGrade prompts you to select a class file to open, remember to click on the List Files of Type list box and select All Files (*.*).
