A method of using a filing cabinet device includes moving a movable divider of a filing cabinet to a desired position for placing files in front of the movable divider; providing a filing cabinet device for the movable divider including a projection that extends a distance W in front of a top of the movable divider; placing files in the filing cabinet between the movable divider and the front of the filing cabinet; and using the projection of the filing cabinet device to orient the files between the movable divider and the front of the filing cabinet so that the bottom of a rear file extends closer to the front of the filing cabinet than the top of the rear file, allowing the files to be easily identified and preventing the files from being packed too tightly together in the filing cabinet.
