The FDS file extension is associated with Final Draft, a screenwriting software application widely used in the film and television industry. An FDS file stores a screenplay, teleplay, or stage play created and formatted within Final Draft. These files contain the text of the script, along with specific formatting elements crucial for screenwriting, such as scene headings, character names, dialogue, action lines, and parentheticals. Final Draft automates many of the formatting rules required by the entertainment industry, ensuring that scripts adhere to professional standards. The FDS format is proprietary to Final Draft, meaning that while other text editors might be able to open the file and display the raw text, they will not be able to interpret or preserve the specific formatting instructions embedded within the file. Therefore, to properly view, edit, and maintain the integrity of an FDS file, it is generally necessary to use Final Draft software.
