Abstract
An improved file folder assembly having an expansible, normally open-top paper-receiving section and a completely removable top cover is provided which allows storage of a number of open top sections for ease of access to the contents thereof while permitting removal of an individual folder and attachment of a top cover thereto during transport and use of the file. In this manner a relatively small number of covers can be maintained for a very large number of file sections, in order to lower costs. The covers are preferably secured to individual folder sections by provisions of mated hook and eye strips respectively mounted on the file sections and covers. On one side of the assembly the attachment strips are vertically and centrally oriented in order to accommodate varying quantities of filed papers, while on the remaining side the strips are horizontally mounted. The uncovered sections can thus be stored in side-by-side relationship and interference between adjacent attachment strips is avoided.
