Caltrans - Engineering Service Center

File Decompression Information



Many of the files on the Engineering Service Center FTP (file server) site are "compressed." To facilitate decompressing these files, we have made many decompression programs available. Every effort is made to ensure that all compression programs have a decompression program available here for Macintosh, Windows, DOS and UNIX based workstations. Please read the file descriptions below and FTP (download) the appropriate file(s).

NOTE: Most of these programs are freeware (no fees involved). Some programs are shareware--they have fees and registration information within the program.

StuffIt Expander 4.5 for Macintosh from the Aladdin website
StuffIt Expander is Aladdin's award-winning freeware product. Use it, as is, to expand StuffIt, Compact Pro, BinHex & MacBinary files. Version 4.5 also now adds the ability to mount ShrinkWrap image files (electronic versions of disks) and to decrypt Private File encrypted files. Add the Expander Enhancer from "DropStuff with Expander Enhancer" and StuffIt Expander is PowerPC accelerated, expands more formats (including .zip and .tar), and joins StuffIt segments. Expander also handles segmented and multipart encoded files (ie: BinHex and UUencoded files). StuffIt Expander has an intelligent background processing scheme that allows expanding groups of files so that you can continue to do other things with your computer.
