Many of the products available from this site are compressed and archived in the UNIX GZIP and TAR formats. Software to uncompress and extract files in these formats are readily available for UNIX platforms (if your UNIX distribution doesn't include these utilities, you can download sources for them from the Free Software Foundation). Users of Windows and Macintosh computers can access these files using freeware or shareware translation/extraction software. Links to non-government software sites are provided here as a service and do not constitute endorsement of the sites by USGS or the U.S. Government.
