What is a tar.z file?

The tar.z extension (often shortened to .taz) denotes a TAR archive compressed using the legacy Unix compress utility. This format relies on the Lempel-Ziv-Welch (LZW) adaptive compression algorithm. Historically significant in early Unix System V environments, it predates the DEFLATE algorithm used in gzip. Due to the patent encumbrances on LZW (Unisys) in the 1990s and lower compression efficiency compared to modern standards, it is technically obsolete but remains in legacy repository archives.

How to open a tar.z file

While the format is deprecated, most Unix-like systems (Linux, BSD, macOS) retain backward compatibility via the uncompress utility or gunzip, which can detect and decompress LZW streams (command: zcat file.tar.z | tar -xvf -). On Windows, 7-Zip provides robust support for opening legacy Z-compressed archives, as does the multi-format archiver IzArc.

What is a TAR file?

The TAR (Tape Archive) format is a file format standardized by POSIX.1-1988 and later POSIX.1-2001 (pax), originally developed for writing data to sequential I/O devices like magnetic tape drives. Unlike modern archive formats, TAR is purely a container format that concatenates multiple files into a single archive without native compression, preserving file system attributes such as user/group permissions, dates, and directory structures. It is frequently paired with compression utilities like Gzip or Bzip2 in Unix-like environments.

How to open a TAR file

Most Unix-based systems (Linux, macOS, BSD) include native support via the GNU Tar command-line utility. Windows does not natively support TAR extraction in versions prior to Windows 10 (Build 17063), requiring third-party tools. For cross-platform compatibility, 7-Zip and WinRAR are standard utilities for inspecting and extracting TAR containers.

# 1. Create job
curl -X POST https://api.runconvert.com/v3/jobs \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "tag": "tar.z-to-tar",
    "tasks": {
      "upload-file": {
        "operation": "import/upload"
      },
      "convert": {
        "operation": "convert",
        "input": "upload-file",
        "output_format": "tar"
      },
