Combining suitcases: To merge all the fonts from one suitcase with another,
drag one suitcase on top of the other. All the fonts from the dragged suitcase
will go into the other, and the dragged suitcase will disappear.
A suitcase can also contain fonts from different font families, although you
should keep all fonts of the same family in the same suitcase. All the fonts
will still appear in menus with their proper names.
You treat a suitcase as you would a folder. To open a suitcase, you double-
click it. To add a font, you drag the font’s icon to the suitcase and drop it in.
To remove a font, you drag its icon out of the suitcase.
To create a font suitcase, duplicate an existing one and throw away its
contents. Then rename the suitcase as appropriate and drag whatever fonts
you want into it.
You cannot have more than 128 font suitcases in the Fonts folder.
Size limits for suitcases: No matter how many fonts you have in a single
suitcase, the Fonts folder counts the suitcase as a single unit. There’s no limit
to the number of fonts in a single suitcase, but the suitcase cannot be larger
than 16 megabytes.
IMPORTANT PostScript fonts cannot be placed in suitcases; they appear as
individual files, loose inside the Fonts folder. Other than the limit imposed by
your system’s memory (RAM), there’s no limit on the number of PostScript
fonts you can have.
