How to Extract TAR.Z Files on Mac

UnFox extracts TAR.Z archives on Mac by decompressing the Unix compress layer and extracting the TAR contents automatically. TAR.Z uses the legacy Unix compress algorithm, which predates gzip. These files are rare in modern use but still appear in legacy Unix software archives and historical source code distributions.

What Is a TAR.Z File?

TAR.Z files use the original Unix compress utility (based on the LZW algorithm) applied to a TAR archive. The .Z extension indicates compression with the compress command, which was the standard Unix compression tool before gzip replaced it in the 1990s. TAR.Z files are found in historical software repositories, old FTP archives, and legacy system backups. The format produces larger compressed files than gzip, bzip2, or LZMA.

How Do You Extract a TAR.Z Archive on Mac?

Drag the .tar.Z file onto UnFox. The app identifies the LZW compression header, decompresses the data, and extracts the TAR contents in a single step. UnFox handles this legacy format with the same drag and drop interface used for modern archives. Progress tracking and disk space validation are included.

TAR.Z is one of nine TAR variants UnFox supports, including modern formats like TAR.ZSTD and TAR.LZ4. all supported TAR variants and compression formats for Mac.

UnFox installs from the Mac App Store and handles legacy TAR.Z extraction without configuration. download UnFox free for Mac from the App Store.
