How to Open XZ, TXZ and TAR.XZ Files on iPhone

XZ is a compressed stream that often wraps TAR in Linux packages. image.raw.xz usually becomes one disk image, while source.tar.xz and .txz commonly become a folder tree. Fileso decodes the xz stream and presents the inner TAR when one is found.

Extract .xz, .txz in Fileso

1. Save the compressed file in Fileso with its full filename and extension.
2. Tap it and choose Extract. Use Extract to Folder if you need a different destination; View prepares a temporary extracted copy for inspection.
3. Wait for decoding to finish. A simple compressed stream may produce one file, while an inner TAR or CPIO produces multiple entries.
4. Open a resulting file and check its size and type before discarding the compressed source.

Plan for more free space than the compressed download occupies. A small .xz may expand into a much larger image or source tree. Use Extract to Folder, wait for the background task to finish, and open a resulting file to verify it.

If extraction fails

A valid extension does not repair a truncated stream or an xz block that needs more resources than the decoder supports. If extraction fails, get a fresh copy or ask for a ZIP or TAR.GZ export. Do not delete the original after a failed attempt.

Common question

Will every XZ file create a folder? No. A plain xz stream normally expands to one file; only a wrapped archive supplies multiple entries.
