file extension FFT - IBM DisplayWrite document file.DisplayWrite was a word processor software application that IBM developed and marketed for its line of IBM PCs. Its document files used the RFT (revisable format text) or DCA (document content architecture) filename extension, both of which were standards on IBM mainframe computers. DisplayWrite's feature set was based on the IBM Displaywriter System, a dedicated microcomputer-based word processing machine. DisplayWrite/370, a much more powerful version with full graphics and WYSIWYG support, is still available for IBM zSeries mainframe computers.
