Had word files alongside the final draft ones in the same folders. Word documents for characters and treatments/synopsis, final draft ones for the actual scripts themselves, and I’ve downloaded libreoffice and it’s able to read the word ones, but not the final draft ones.
The final drafts are word files? Google docs may open it. Have you tried simply copying the file and changing the file name. Ie finaldraft.txt
I rember this working for simple files long shot I know. Good luck
