Generally, a file by using the .tar.gz is a file which has been created by simply using Unix-based archival application tar and then compressed by using the gzip compression. These files are often referred as the “tarballs,” and you can easily find them with just a double extension. This extension can also be shortened to the .tgz or.gz.
Tar files are normally used by the macOS and Ubuntu users for data archival and backup purposes. But sometimes Windows 10 users may also come across these types of files and need to extract its content. Although you can also use some third-party applications like 7-Zip and many more, sometimes these applications don’t work well with the files which are created on another platform, and they were also very slow to uncompressed a large number of files together.
