One file per driver, eight pieces, named in §391.51. Most files that fail an auditor are not missing the famous pieces — they are missing the small dated ones, or carrying a dead form in place of a living duty. Here is the file, piece by piece.

Older checklists and older kits include an annual “list of violations” the driver signs, listing his year's tickets. That certification was removed from the required contents of this file — the old §391.27 duty no longer exists. Keeping the form harms nothing. Believing it replaces pieces 4 and 5 fails audits: the living duty is the annual MVR pull and the reviewer's note.
The previous-employer safety-history checks — the driver's authorization, your inquiries to his driving employers of the last 3 years, their answers or your documented attempts — do not belong in this file. They live in a separate, access-limited investigation-history file (§391.53). Auditors ask for both files. Folding them together mis-teaches the structure and exposes history answers to people the rule keeps them from.
The DQ file is kept for the driver's whole employment plus 3 years (§391.51(c)). The dated pieces — annual records, review notes, medical proof, registry notes — may be removed 3 years after they were made (§391.51(d)). Keep the pieces in date order and both rules become a filing habit instead of a project.
The DQ file is the most-sampled file in the audit, but it is one sample among several. The free New Entrant Audit Verdict scores the file alongside the 16 automatic-failure lines and every other sampled file. The fillable packet itself — application, road test certificate, review note, trackers — is §2 and §3 of the Audit & DQ Kit.
