Apple IIe Card - Manual (Page 72)

When you’re in the Macintosh environment, you can only give files on
Apple IIe disks legal ProDOS names, with two exceptions:
■
You can use spaces in the names. When you view a filename that
contains spaces in the Apple IIe environment, the spaces are
automatically converted to periods. For example, the name “MY FILE”
in the Macintosh environment would appear as “MY.FILE” in the
Apple IIe environment.
■
You can use lowercase letters in the names. When you view a filename
that contains lowercase letters in the Apple IIe environment, the
letters are automatically converted to uppercase. For example, the
name “File” in the Macintosh environment would appear as “FILE”
in the Apple IIe environment.
You may be able to use your Macintosh programs to view and edit your
Apple IIe files. For example, if you wrote a letter using an Apple IIe
program, you might be able to edit the letter with your Macintosh word
processor.
