Takeoff File Maintenance (TFM) lets you quickly review and modify items previously taken off. It should be included in your Takeoff display configuration since it acts as an on-screen audit trail of your takeoff. See Takeoff Screen View Layouts in the Estimating Help for how to configure your Takeoff display.
This file contains all the items you have taken off so far in this Section.
