How to open .PAS files on Android
To open .PAS files on Android, open the .pas file with a text/code editor app to view it as plain text; for building/compiling, move the file to a desktop Pascal toolchain/IDE.
Step-by-step instructions
- Open the .pas file with a text/code editor app to view it as plain text; for building/compiling, move the file to a desktop Pascal toolchain/IDE.
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.
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.
