QuickTime movies must be stored on a local or remote HFS disk drive in order to run; this means that a movie that resides on the remote Image server must be completely transferred to a local scratch disk before it can be played. The client does not attempt to manage the space used in this manner, so that if many movies are accessed in a single session it is possible to fill all the space available.

Typical configurations

network server/local hard disk/CD-ROM:
- set a relative path prefix ":" or "subject:", expecting the user to double-click a file
- set movie map name to ":subject:Index:movie.map" or whatever

Data on CD-ROM, app on hard disk:
- set an absolute path prefix "CD volume name:"

Index of file operations

A table I built while trying to make sense of what kinds of files are accessed by what names and mechanisms. Shorthand used in the table below:
%pathprefix is a string set by the (set-path-prefix) configuration command, and is usually a single colon to indicate that files are to be accessed relative to the "current directory", the one the startup icon is in
%index is normally "Index:", changed by modifying a STR# resource
%glossary is normally "Descriptions:", changed by modifying a STR# resource
%name, %discname are runtime strings passed in by the calling routines
