How to open .PAS files on iOS
To open .PAS files on iOS, open the .pas file in the Files app with a text/code viewer; if it won’t preview well, share it to a dedicated text editor app or transfer it to a desktop to compile/run.
Step-by-step instructions
- Open the .pas file in the Files app with a text/code viewer; if it won’t preview well, share it to a dedicated text editor app or transfer it to a desktop to compile/run.
Common issues
The .PAS file opens in the wrong app (or as an unknown file)
Your system may not have a Pascal-aware editor/IDE associated with .pas, so it defaults to an unrelated app or shows “unknown format.”
- Use “Open with” and select a text/code editor to view the file content.
- If you regularly work with Pascal, set your chosen editor/IDE as the default app for .pas files.
It’s not actually Pascal source code
Sometimes files are mislabeled or downloaded with the wrong extension; a .pas should typically be readable text containing Pascal/Object Pascal keywords (e.g., unit, interface, implementation, begin, end).
- Open the file in a plain text editor and verify it looks like Pascal source code.
- If it looks like binary/garbled data, re-download the file or ask the sender what program created it.
Compiler/IDE errors when building a .PAS file
A .pas file is usually part of a larger project (units depend on other units, project files, and library paths). Opening a single unit may not be enough to compile successfully.
- Obtain the full project (all referenced units and supporting files), not just one .pas file.
- In Delphi workflows, open the project in Delphi/RAD Studio rather than compiling a single unit in isolation.

Recover a deleted or lost .PAS 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
.PAS files are plain text source code, but they may be part of a project that builds an executable; treat code from untrusted sources as potentially harmful if compiled and run.
