Is There a Portable Version of MP4Joiner?
No — there is no official portable version of MP4Joiner. The project’s SourceForge release for the current version, MP4Tools 3.8, contains exactly three files: a Windows installer (MP4Tools-3.8-win32.exe), a Mac disk image (MP4Tools-3.8-MacOSX.dmg), and the source archive (MP4Tools-3.8.tar.bz2). No ZIP-and-run portable build exists among them.
The PAD confusion, cleared up
The official website’s download area mentions a “Portable Application Description”. That is a PAD file (pad.xml) — a standard metadata description that software directories use to describe a program. “Portable” in that name refers to the description format being portable between directory sites, not to a portable edition of the software. It is not a download you can run.
What about portable repacks on other sites?
Third-party sites do offer “MP4Joiner portable” repacks. We have not verified any of them, we do not endorse them, and we will not link them: an unofficial repack of an installer-based program can bundle anything, and there is no official hash to check it against. The verifiable official Windows file is the installer above (24,156,961 bytes; SHA-256 e369f3c39e74ca6e106767817b63179c59d030497dde01cfb1e9f64393a0247b).
Safe alternatives
- Just install it. The normal install is quick, free (GNU GPL), and installs both MP4Joiner and MP4Splitter — see MP4Joiner for Windows.
- Build from source. The official source archive is the route for anyone who wants full control over what runs on their machine.
- Check the release record. The version history shows every official release since 2015 — no portable edition appears in any of them.
