How to Open GZIP (.gz) Files

GZIPとは？

GZIP is a compression format commonly used on Unix and Linux systems. It uses the deflate algorithm (same as ZIP) to compress individual files.

GZIP files have the .gz extension. A file named "document.txt" compressed with gzip becomes "document.txt.gz".

GZIP is often combined with TAR to create .tar.gz (or .tgz) archives — TAR bundles the files, GZIP compresses the bundle. This is the most common archive format on Linux.

7-ZipでGZIPを開ける？

7-Zip can create and extract GZIP files, achieving 2-10% better compression than the standard gzip utility.

7-Zip handles .tar.gz (and .tgz) files transparently — both TAR and GZIP layers are processed in a single operation.

7-Zip can also create .tar.gz archives directly by selecting "gzip" as the archive format.

GZIPの解凍方法

Right-click the .gz file

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

Choose extraction option

Select "Extract Here" to extract the compressed file. For .tar.gz, 7-Zip handles both gzip and tar layers automatically.

Access extracted files

The decompressed file appears in the destination folder. For .gz files, the original filename is restored (minus the .gz extension).

GZIPの作成方法

Select file(s) to compress

GZIP compresses individual files. Select the file you want to compress in Windows Explorer.

Open the archive dialog

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

Create the .gz file

Click OK. 7-Zip creates a .gz compressed file with better compression than standard gzip.

GZIPのパスワード保護

GZIP does not support password protection or encryption.

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

GZIPのよくあるエラー

Cannot extract .gz file

原因: File corruption or unsupported format variant.

解決策: Re-download the file. 7-Zip supports standard GZIP. If the file uses an uncommon extension, you may need the original compression tool.

GZIP FAQ

What is a .gz file?

A .gz file is a file compressed with GZIP, a common compression format on Unix/Linux. It compresses individual files. When combined with TAR, it creates .tar.gz archives.

Can 7-Zip open .gz files?

Yes. 7-Zip can extract .gz and .tar.gz files on Windows. It handles both GZIP and TAR layers automatically for .tar.gz files.

Can 7-Zip create .gz files?

Yes. 7-Zip can create GZIP compressed files. Right-click > 7-Zip > Add to archive > select "gzip" format.

What is .tar.gz?

A .tar.gz file is a TAR archive compressed with GZIP. TAR bundles multiple files, GZIP compresses the bundle. It's the standard archive format on Linux.

Is GZIP better than 7z?

For compression ratio, 7z is significantly better (30-50% smaller). GZIP is more compatible on Unix/Linux systems. Use 7z for best compression, GZIP for Linux compatibility.
