Blueberry Software's Filtrix converts text and graphics from one format to another. Choose among formats such as Framemaker, Word, HTML, Wordperfect , Interleaf , and many others. It converts text, styles and formats, headers and footers, footnotes, autonumbers, tables, and graphics. Filtrix is available for Windows and UNIX. If you're interested in trying it, download the free demo.

If Framemaker is your source document format, save the file in MIF format before converting.  If it's Interleaf, save as IAF . For Quicksilver documents, if the "Save As" menu does not show "Release ASCII 6", then select Tools->Preferences->File and enable the "Show Full List of Format Choices for File Save As" setting, then save the document as Interleaf Release ASCII 6 before translating.

Filtrix reads and writes Word native format, so don't save as RTF.
