.UZIP File

Compressed disk image created by mkuzip, a FreeBSD compression utility; compresses a disk image, such as a .UFS file, so that it can be read during runtime by the FreeBSD geom_uzip utility; used to reduce the disk image file size at the expense of additional CPU time when reading the image.

UFS files are stored with a small script at the beginning of the image. This allows them to be run like any other shell script.

UZIP files may be seen with the multiple file extension .UFS.UZIP.
