UPCToISBN converts the UPC (Universal Product Code) from a book into it's equivalent ISBN (International Standard Book Number). It's most useful when used with a barcode scanner to easily catalog a number of books: UPCs converted are logged to a text view component for copying and pasting into a book cataloging program (such as Books or LIbrary).
Folder Size Catalog provides at-a-glance view of your folders and folder sizes so that you can easily check the distribution of your disk space.
