First of all, the correct command is

	% tar xvf file.7z

In case you don't specify a file name (f), tar will
assumes the system's default tape drive /dev/sa0,
because tar is the "tape archiver". :-)

See "man tar" for details.

In case tar cannot uncompress the 7zip format, install
the p7zip port. See "man 7z" for details (extract with
e or u function).
