DOS to Macintosh File Conversion

When you transfer files from a Windows PC to a Macintosh, the DOS file extension must be mapped to a Macintosh Type and Creator in order for the file to be read correctly on the Macintosh.

The following procedure explains how to add a new file mapping extension. When you transfer a file with the specified extension from a PC to a Macintosh, the file will have the correct Type and Creator when it is saved on the Macintosh.

To map DOS file names to Macintosh Type and Creator

  1. Find out the Macintosh Type for the document you will be transferring from the Windows computer to the Macintosh. To do this, find a file on the Macintosh that was created by the same software as the file on the PC. Open it with a utility such as ResEdit or Find File, and choose Get Info from the File menu. Alternatively, use Find File, select More Choices, use the down arrow by Name, and select Type.

  2. Using a DOS or Windows editor, open the filemap.ini file. It should be in the Timbuktu Pro directory on your Windows computer.

  3. Find the [PC To Macintosh] section.

  4. Add your new entry just before the last entry in the list and use the mapping number of the last entry. Use the following example as a model:

    FileMapping56=“SAFR” * “SFII” “SFR” “0” ; Comments
     
    In this example, FileMapping56= is the label for this line; if 56 was not the last number in the list when you began this procedure, use the actual last number in the label instead of 56.
     
    SAFR
    is the Type value you want the file to have when it is saved on the Macintosh.
     
    SFII
    is the Creator value you want the file to have when it is saved on the Macintosh.
     
    SFR
    is the 3-character DOS extension with which the document was saved on the Windows computer.
     
    0
    is a field reserved for future development; leave it as it is.
     
    It is important that you match the spacing on your new line to the spacing used on the previous lines in the filemap.ini file.

  5. Change the mapping number on the last entry to one number greater than its previous value. For example, if the last entry was "FileMapping56", change it to "FileMapping57".

  6. Save the changes to the filemap.ini file.

  7. Restart Timbuktu Pro.
