FAQ: Disk Space
How much disk space does Sketchpad version 4 require?
On Macintosh, a minimum (application-only) installation requires 1.3MB and a full installation requires approximately 17MB (2MB for application, 3MB for sample documents, 1MB for JavaSketchpad, and 11MB for Sketchpad Help).
On Windows, a minimum (application-only) installation requires 2MB and a full installation requires approximately 15MB (2MB for application, 3MB for sample documents, 0.5MB for JavaSketchpad, and 9.5MB for Sketchpad Help).
On both platforms, the software may be installed using an Installer program, or by drag-and-drop from the CD-ROM. Both platforms can also execute the software directly from the CD-ROM, which is slower than installing it on your hard disk but requires no hard-disk space.
