(only sysop, option DF3VI_EXTRACT in config.h)
Syntax: EXTRACT [<boardname>] [<range>]

Extract can be used to save BIN and 7PLUS files from mails. The files are
saved in TEMP directory of BCM ("/bcm/temp"). BIN and 7PLUS files will be
overwritten merciless! If a BIN filename is missing, a new one will be
created. Go/Stop marks of 7plus files are not saved. Existing files are not
replaced but their extension will count up.
