What is the size of SuperMemo collections in KB?
For early versions of SuperMemo it used to be (5+0.1*Total) KB, where Total is the number of text elements in the collection (additionally sounds used to contribute 10-20 KB per word and pictures 20 KB per picture). SuperMemo 8 introduced extensive object indexing in the form of registries and made it possible to add a great deal of multimedia files. Although indexing reduces the size of multimedia collections, the basic size of collections increased substantially to 0.5*Total KB for standard question-and-answer collections (a five-fold increase).
