System.

Cross Platform Issues
Can they Co-exists?
Inside a Macintosh
• Reads some invisible or
hidden code embedded
your document.
• The code has TYPE and
CREATOR information
to identify the
application which
created the file.
Inside the PC
• Reads the three character
filename extension on the
document.
• An extension map tells
the computer the
application that created
your file.

Sharing Files Across Platforms
• Use the same software application on both
platforms.
• Use the filename extension (.doc, .xls, .cwk)
-even on the MAC.
• If not using the same application - save file
as ASC text or Rich Text File (RTF)
• Use the “Save As” function under the File
Menu
Mounting Disks
• Apple: Has a “Super Drive” and Apple File
Exchange or PC Exchange. MACs
(PowerPC Macs) will see and format
Macintosh or PC disks.
• PCs: Only recognizes PC formatted disks, it
will try to erase MAC disks. With third
party software (MacOpener), PCs will
mount all disks.
In the Multi-Platform World
• Always use a PC formatted
disk when you are not sure
where you will have to use
your document.
• Use the Standard
applications.
• Always use the filemane
extension.
