Also found in: Acronyms, Wikipedia.
file control block
(operating system)(FCB) An
MS-DOS data structure that
stores information about an open file. The number of FCBs is
configured in
CONFIG.SYS with a command
FCBS=x,y
where x (between 1 and 255 inclusive, default 4) specifies the
number of file control blocks to allocate and therefore the
number of files that MS-DOS can have open at one time. y (not
needed from DOS 5.0 onward) specifies the number of files to
be closed automatically if all x are in use.
