The fiocompress utility is a file compression tool that works together with the dcfs(4FS) file system to perform per-file compression. You can use fiocompress to decompress a compressed file or mark a compressed file as compressed, causing automatic decompression on read. The primary use of fiocompress is to compress files in the boot archive.
Note that this utility is not a Committed interface. See attributes(7).

This compression/decompression utility works only with files stored in a UFS file system.
There is no obvious way to determine whether a given file is compressed, other than copying the file and comparing the number of disk blocks of the copy against the original.
