FILE (Fr. file, a row, Lat. filum, Ital. fila, filo), in a military sense, is used to signify any line of men standing directly behind each other, as rank refers to men standing beside one another. In ordinary formations of the present day, a battalion stands two deep, or in two ranks—front and rearwherefore a file consists of two men. Sometimes, however, the battalion may be formed much more solidly, as in a square, when the file comprises a far larger number. The number of files in a company describes its width, as the number of ranks does its depth : thus, 100 men in 'fours deep' would be spoken of as 25 files in 4 ranks.
