Synopsis:

The minor attention this short film has attracted derives from its having been the first production directed by influential female documentarist Kay Mander, for the Shell Film Unit. It is perhaps best appreciated as a skilful contribution to its genre - the technical instructional film, but is also interesting in the context of Mander's later career, especially regarding the adventurous use of the camera such as in in its incorporation of tracking shots. The purpose of technical instructional films was to convey to a clearly identified target audience (whether in the general public, or in a particular field of work) exactly how to undertake a specific task. Indeed, the history of instructional filmmaking is littered with film titles beginning 'How to...' - from How to Dig (1941) to How to Cook Green Vegetables (1944). The target audience for How to File was metalwork apprentices and its subject the basic techniques of using a metal file to smooth and shape raw metal materials. In a mere eight minutes it explains the basic principles of filing and shows its viewers how to position and hold a file, how to move over the material being shaped, different types of file, and - characteristically of the best instructional films - how to maintain accuracy. Metalwork was critical to the war effort but remained important in Britain's postwar industrial heyday; this film remained in Shell's distribution library for some 25 years, though it was no doubt occasionally mis-booked by employers wanting an instructional film covering basic secretarial practice.
