How to open .FLY files on iOS
To open .FLY files on iOS, in the Files app, try Quick Look first; if it doesn’t preview correctly, share/open the file in a text-editor app to view it as plain text.
Step-by-step instructions
- In the Files app, try Quick Look first; if it doesn’t preview correctly, share/open the file in a text-editor app to view it as plain text.
- If the file is application-specific (not readable as text), transfer it to a desktop system and open it with the originating software.
Common issues
The .FLY file opens as unreadable text or gibberish
Some .FLY files are specialized text (templates/preprocessor content) or use a character encoding your viewer didn’t detect.
- Try a different text editor that allows selecting encoding (UTF-8, Windows-1252, etc.) and reopen the file.
- Look at the first lines for clues (headers/keywords) that identify the producing tool, then open it with that tool if available.
No app is associated with .FLY (nothing happens or you’re prompted to choose an app)
.FLY is not universally supported by default applications, even though it is often treated as text.
- Choose a plain-text editor to open it for viewing and identification.
- If it’s a Digiflyer Studio e-mail document, obtain/access the originating software environment and open it there.
The file was sent as a “document” but contains markup/template content
.FLY may represent text preprocessor content; it’s not the same as Word/PDF documents and may require the appropriate processing tool to render output.
- Ask the sender what program created it and whether they can export to a more common format (PDF/HTML/TXT).
- If you only need to read it, open in a text editor to view the source content.
File association on Linux doesn’t behave as expected
Linux desktop associations are often driven by shared-mime-info rules (MIME-to-extension mappings), which may not be installed or may differ by distribution.
- Check the file’s detected type in your file manager properties and try opening with a text editor explicitly.
- If needed, adjust the default application for this file type in your desktop’s settings.

Recover a deleted or lost .FLY file
If the file was deleted by mistake or the drive was formatted, data recovery software may be able to get it back. Stop writing to that drive right away, because new data can overwrite what you want to recover.

Security note
.FLY is commonly treated as text (text/vnd.fly), so it typically does not execute by itself; however, be cautious with files from unknown sources because applications that parse specialized text formats can still have vulnerabilities.
