The only file type the Go app or the Mobile App can open is FDX, the format used by Final Draft 8 and later. It does not open FDR (Final Draft 7 / 6 / 5), RTF, DOC, DOCX, TXT, HTML or PDF files.
The Mobile app cannot open text files created in Final Draft.
Some other screenwriting programs can save as FDX, but these files are not written in genuine Final Draft FDX and the scripts may not look or behave as expected when opened in Final Draft 8 or later or the Final Draft Mobile App.
