How to Open an FDX File on iPhone (Files, Mail, AirDrop)

How to open an FDX on iPhone: the short answer

iOS has no built-in reader for Final Draft files, so tapping an .fdx shows a blank preview or a wall of XML tags. The file is fine. You need to hand it to an app that understands it, and on an iPhone that hand-off is always the share sheet.

1. Get the .fdx into the Files app, from Mail, Messages, AirDrop, iCloud Drive or a download.
2. Press and hold the file and tap Share.
3. Choose Zen Writer from the app row. The screenplay opens formatted, with sluglines, dialogue indents and transitions where they belong.

If you only need to read the script and would rather not install anything, open the free FDX viewer in Safari and pick the file from Files. Both routes, and the ones from Mail and AirDrop, are below; every platform's options are summarised in how to open an FDX file. For what the file actually is, see what is an FDX file.

Open an FDX from the Files app

Files is the hub for every route on this page, so it is worth learning the one gesture properly.

1. Open Files and find the .fdx. Downloads from Safari land in On My iPhone > Downloads; anything synced from a Mac is under iCloud Drive.
2. Do not just tap it. A single tap opens Quick Look, which cannot render FDX and shows a document icon or raw tags. That is expected.
3. Press and hold the file, then choose Share. You can also tap the file, then tap the share button in the top corner of the Quick Look screen.
4. In the share sheet, look at the row of app icons under the file name. Tap Zen Writer. If it is not visible, scroll the row to the right and tap More.

iOS only lists apps that declare they can open the FDX document type, which is why a share sheet crowded with apps for a photo offers almost nothing for a screenplay. If the row is empty, no app on the phone can read the file. Installing Zen Writer for iPhone fixes that; it is free, needs no account, and the script stays on the phone.

One habit that saves confusion: apps use the filename as the script title, so rename the draft in Files before you import it. NORTH_POINT_draft4.fdx is a better title than the name your collaborator's laptop generated.

Open an FDX from a Mail attachment

Tapping an .fdx attachment in Mail hands it to Quick Look, exactly as tapping it in Files does. You get the XML, a blank sheet, or an offer to save it. There is no Mail setting that changes this. What works:

• Press and hold the attachment, choose Share, and pick Zen Writer from the app row. Messages behaves the same way: tap the file to open the preview, then use the share button in that preview.
• Save to Files first if you will read the script more than once. Attachments live inside the mail store, and it is easy to lose track of which draft you were looking at. Choose Save to Files from the share sheet, then open it from Files as above.
• Gmail, Outlook and other mail apps keep attachments in their own viewer. The hand-off is still the share icon, then Save to Files or Zen Writer directly.

A feature script is a few hundred kilobytes, because FDX carries text and no images, so saving a copy costs nothing. If the attachment arrives as .fdx.zip, tap it once in Files to unzip, then share the .fdx inside.

AirDrop an FDX from a Mac

When the script is on a Mac you own, AirDrop is faster than any cloud step. Right-click the .fdx in Finder, choose Share > AirDrop, and tap the iPhone. Because the transfer is text, a 120-page feature arrives in about a second.

What happens next depends on the phone. If an FDX-capable app is installed, iOS offers an Open with prompt on arrival and you can pick Zen Writer directly. If not, the file lands in Files > Downloads and you use the share sheet from there.

Two details that save a minute:

• If the Mac and the iPhone use different Apple accounts, set the phone's AirDrop to Everyone for 10 Minutes. Otherwise the Mac will not list the phone and it looks as if AirDrop is broken.
• The original stays on the Mac untouched. You now have two copies, so decide which one is the working draft before you edit either.

Finder's cable-based File Sharing panel only shows apps that publish a Documents folder, which most screenplay apps do not. AirDrop and iCloud Drive are the practical routes. The Mac side of this workflow has its own page.

Read an FDX in Safari with nothing installed

The free FDX viewer renders a script in the browser: tap the file chooser, pick Browse, and select the draft from Files or iCloud Drive. You get a screenplay laid out on a page, with a scene list to jump around and a page count, and no account to create.

It is built for one job. You are on a location scout, a producer emails a draft, and you need to read the three scenes that shoot tomorrow. It is read-only, so it will not help the moment you want to change a line. It also cannot export FDX back. For anything beyond reading, the app is the tool.

If you want a copy you can forward to someone who has nothing but a phone, the free FDX to PDF converter gives you a fixed document that Mail, Messages and Quick Look all display correctly.

Final Draft's iPhone app vs free options

Final Draft publishes its own iOS app. It opens FDX natively, and it is a paid app: check the App Store for the current price. If you already work in Final Draft on a desktop and want its exact feature set on the phone, it is a reasonable purchase.

You do not need it to open a Final Draft file. FDX is plain XML, and Zen Writer imports it for free, edits it with automatic formatting, and exports FDX back. The realistic comparison for a writer who does not own Final Draft:

Reading vs editing an FDX on a phone, and exporting it back

At iPhone width a page of Courier wraps into a narrow column. You can read one scene that way comfortably; reading a whole feature is work, and true page breaks depend on the app. What a phone is genuinely good for:

• Reading your own draft away from the desk, where you cannot start fixing things.
• Checking one page before a call. Search finds the line; the scene navigator jumps to the scene.
• Surgical edits. The tightened joke, the name change that has to happen everywhere. Zen Writer formats the element as you type, so a fix on the phone does not damage the layout.
• Running lines with an actor, using the character list to jump between speeches.

When you have edited, export FDX from Zen Writer and share it straight from the export sheet by Mail, Messages or AirDrop. The file goes back in the format it arrived in, so a Final Draft user opens it as a normal script. What survives the round trip and what to check before sending is in editing an FDX without Final Draft.

Mistakes that cost time on a phone:

1. Tapping the file repeatedly. Quick Look will never render it. Use Share.
2. Uploading it to Google Docs. Docs has no FDX importer and produces a page of tags.
3. Editing the wrong copy. Mail attachment, Downloads and iCloud Drive can each hold a version. Pick one folder and keep the draft there.
4. Sending a watermarked export as a deliverable. Fine for a look, wrong for a submission.
