filenamegz

A filename ending with .gz typically indicates that the file has been compressed using the gzip compression algorithm. Gzip is a common utility used for file compression on Unix-like operating systems, though it is also available for other platforms. Its primary purpose is to reduce the size of a file, making it quicker to transfer over networks or consume less storage space.

When a file is compressed with gzip, the original file is replaced by a new file with the .gz extension. To access the original content, the file must be decompressed using a corresponding gzip utility. For example, on a Linux or macOS system, the command gunzip filename.gz would decompress the file, restoring it to its original state. On Windows, various third-party archiving tools like 7-Zip or WinRAR can also handle .gz files.

The .gz format is widely used for compressing single files. It is often seen in conjunction with other archiving tools, such as tar, where multiple files are first bundled together into a .tar archive and then compressed with gzip to create a .tar.gz file. This combination is a standard way to distribute software or data. While gzip offers good compression ratios, it is a lossless compression method, meaning no data is lost during the compression and decompression process.
