Where a large number of folded documents are to be filed, as in the office of a corporation using a voucher system, this file is much more convenient than the old style. An old-style document file has a limited filing capacity, and must be taken from the cabinet for consultation. A vertical file drawer, legal size, provides three compartments, each 24" in length. This gives an actual filing capacity of six feet in a single drawer. An upright section, equipped for document filing, is shown in Fig. 31. If an entire section is not needed for this purpose, one drawer can be equipped for document filing, and the others used for correspondence.

A style of construction designed to combine the expansion idea with variety is known as the inter-inter cabinet. This cabinet consists primarily of an outer cabinet or shell of standard height, depth, and width. This shell is divided into compartments of standard height into which the filing devices are fitted. The various filing devices are arranged in skeleton units of standard dimensions, made interchangeable so that any desired combination can be produced. Fig. 32 shows an outside cabinet, card index, and vertical file units, which fit the openings in the cabinet.

This construction enables the user to make a combination of small units of various kinds to suit present requirements, all housed in a single case in a compact form. Provision for future expansion is unnecessary, since an additional outside cabinet can be added at any time, and the units rearranged at will to conform with changes in the system.
