Under Microsoft Windows '95, Powerpoint uses graphic input
filters to read most formatted graphics files. These file names
typically are named:
These filters are scattered in various subdirectories on the hard drive, and are not necessarily all stored in the same location since they may be installed by (and can be used by) more than one type of application. For example, I discovered that installing the Microsoft Word Internet Assistant added a filter that allows Powerpoint to read JPEG files.
Given the interdependence of the various components of the Microsoft Windows environment, it is dangerous to assume that features that are present on the machine in your office will be present on machines in the student computer labs. If you are teaching a class under these conditions, it is a good idea to verify that the features that are essential for your application are present on these machines.
