How to Open TAR Files with 7-Zip

TARとは？

A TAR file is an archive format commonly used on Unix and Linux systems. TAR (Tape Archive) was originally designed for tape backup but is now used for general file bundling.

TAR files bundle multiple files into a single archive without compression. They are often combined with compression formats like gzip (.tar.gz or .tgz), bzip2 (.tar.bz2), or xz (.tar.xz).

TAR preserves Unix file metadata including permissions, ownership, timestamps, and symbolic links, making it ideal for Linux software distribution and backups.

7-ZipでTARを開ける？

7-Zip can create and extract TAR files with full POSIX metadata support (permissions, ownership, symlinks).

7-Zip handles compressed TAR formats transparently: .tar.gz, .tar.bz2, .tar.xz are extracted in a single operation.

7-Zip can create .tar.gz and .tar.xz archives directly, combining TAR bundling with gzip or xz compression.

TARの解凍方法

Right-click the TAR file

Locate your .tar, .tar.gz, or .tar.xz file in Windows Explorer, right-click it, and navigate to "7-Zip".

Choose extraction option

Select "Extract Here" to extract in the current folder. For .tar.gz files, 7-Zip handles both layers (gzip + tar) automatically.

Access extracted files

Files are extracted with their original directory structure. On Windows, Unix permissions may not be fully applicable.

TARの作成方法

Select files to archive

Select the file(s) or folder(s) you want to bundle into a TAR archive.

Open the archive dialog

Right-click > 7-Zip > "Add to archive..." and set the format to "tar".

Create compressed TAR (optional)

For compressed archives, set format to "gzip" or "xz" — 7-Zip automatically creates a .tar.gz or .tar.xz file.

Create the archive

Click OK. 7-Zip creates the TAR file (uncompressed) or compressed variant.

TARのパスワード保護

TAR format does not support password protection or encryption.

For secure archives, use 7z or ZIP format with AES-256 encryption instead.

Alternatively, encrypt a TAR file by placing it inside a password-protected 7z archive.

TARのよくあるエラー

Cannot extract .tar.gz file

原因: Software doesn't handle dual-layer compression.

解決策: 7-Zip handles .tar.gz transparently — right-click and extract. If using other software, you may need to extract gzip first, then extract the resulting .tar file.

TAR file extraction shows permission errors on Windows

原因: Windows doesn't support Unix file permissions.

解決策: This is normal on Windows. The files extract correctly but Unix-specific permissions (like executable bits) don't apply. This doesn't affect file contents.

TAR FAQ

What is a TAR file?

A TAR file is an archive format used on Unix/Linux systems. It bundles multiple files into one without compression. TAR files are often compressed with gzip (.tar.gz) or xz (.tar.xz).

Can 7-Zip open TAR files?

Yes. 7-Zip can open and extract TAR, .tar.gz, .tar.bz2, and .tar.xz files on Windows with full POSIX metadata support.

Can 7-Zip create TAR files?

Yes. 7-Zip can create TAR archives and also compressed variants (.tar.gz, .tar.xz). Right-click > 7-Zip > Add to archive and select the format.

What is .tar.gz?

A .tar.gz file is a TAR archive compressed with gzip. It's a two-layer format: gzip compresses the TAR bundle. 7-Zip handles both layers automatically during extraction.

Can Windows open TAR files?

Windows 10/11 can open some TAR files natively, but 7-Zip provides better support including .tar.gz, .tar.xz, and POSIX metadata handling.

Is TAR compressed?

TAR itself does not compress — it only bundles files. Compression is provided by external tools: gzip (.tar.gz), bzip2 (.tar.bz2), or xz (.tar.xz).
