Apple System 7.1 - Manual (Page 4)

3. Drag across the box containing the number you want to change (either "Minimum size"
or "Preferred size").
The preferred size can't be smaller than the minimum size.
4. Type the number of kilobytes (L) of memory you want the program to set aside for
itself.
If you find that the program frequently runs out of memory, try increasing both the
preferred size and the minimum size.
If you want a program to open even if the available memory is less than the minimum size,
you can lower the minimum size. If the size you type is smaller than the suggested size,
some programs will perform acceptably, but others may show performance problems or not
work at all.
5. Close the Info window.
If you typed a number smaller than the "Suggested size," you'll see a message asking you
to confirm your decision.
Using Macintosh File Sharing
The first time you turn on Macintosh file sharing in System 7.1, the setting that allows
guest access is turned off. ("ou turn guest access on or off in the Users & Groups
control panel.)
In version 7.0, guest access was turned on by default.
As a result of this change, after you share a folder or disk with the Sharing command in
the File menu, the folder or disk is still accessible only to you.
To make the item accessible to others, you have to
- explicitly give access to registered users or groups, or
- turn guest access on in the Users & Groups control panel
The QuickTime extension
The QuickTime extension adds capabilities that let your application programs integrate
graphics, sound, video, and animation into documents.
By providing a standard way for all Macintosh programs to control these multimedia
elements, QuickTime increases their compatibility and makes them easier to use.
The QuickTime extension manages
- how programs let you view, control, and edit QuickTime movie files (a QuickTime movie
can include any combination of video, animation, and sound)
- how programs control the compression of movies and still images (compression reduces
the amount of space needed to store a file)
- how programs control hardware that interacts with QuickTime (for example, an expansion
card for capturing input from a video camera)
