The most notable change is that the Browser is now compatible with Mac OS 8. StuffIt Deluxe 4.5 is a modest improvement over version 4.0, the first product I reviewed after joining the ATPM staff a little more than two years ago. 'compressed' to refer to SpaceSaver compressed files. Aladdin uses the terms 'archived' and 'stuffed' to refer to files compressed with StuffIt Deluxe, and the word StuffIt SpaceSaver, the other component of the StuffIt Deluxe package, is an automatic compression program that uses a different compression routines than StuffIt Deluxe and is designed to transparently increase the capacity of your hard disk. It is the main component of the package, and when people refer to a file that is stuffed, or if you see a file whose name ends in '.sit', the file in question is compressed with StuffIt Deluxe.

Compressing files can take anywhere from seconds to minutes to hours, depending on how large the file is, what speed computer it is being compressed on, and several other factors. Large text files usually compress a bit more than this, while JPEG graphics files and QuickTime movies (which already employ their own sort of compression) don't compress as much. There are many ways of doing this, and I don't have space to go into detail here, but the result of compression is that the file is usually reduced to about 50% of its original size. It is also useful for squeezing more data onto hard disks.Ĭompression programs make files smaller by finding more efficient ways of representing the data they contain. It reduces the number of floppy disks or removable cartridges needed to hold files and allows large files to be spread across multiple disks. It can speed up transfers of files over modems and networks by reducing the amount of data that needs to be sent.
