This utility program can help you extract compressed files and create your own compressed files in several different formats. This software can be used on any computer, including the ones in a commercial organization. a] Open TGZ files with 7-Zipħ-Zip is a free, open-source file archiver with a high compression ratio. You can use third-party software to extract compressed files. Let’s look at these two methods in detail. In addition to external apps, Windows 10 includes native support for TAR which can help you extract TAR files using simple Command Prompts. They can be extracted using third-party applications like 7-Zip and PeaZip which are free and open-sourced. But they are sometimes used for regular data archiving purposes hence, Windows 11/10 users may also come across such types of files and may need to extract their content.Įxtracting a. files are typically seen with software installers on Unix-based operating systems like Ubuntu and macOS for data archival and backups. TAR files are often compressed once created the compressed TAR files are called tarballs and sometimes use a “double” extension like “.TAR.GZ” but are usually shortened to “.TGZ” or “.GZ”. These files are made up of a collection of files placed in a TAR archive mainly for making storage and tracking easy. Or implement everything from the ground floor.A file with the TGZ or GZ file extension is created using the Unix-based archival application tar and further compressed using GZIP Compression. you have to consider for a third party library such as NET libraries for compressing or even decompressing cause you can't even make a generic compress file or even decompress a generic zip file. if you decompress any docx file with package class you can see everything stored in it. It something Microsoft uses to compress their *x extension office files. NET 2.Īnd there is another way which is Package class it's actually same as Gzipstream and DeflatStream the only different is you can compress multiple files which then can be opened with winzip/ winrar, 7zip.so that's all. gz format so if you compressed any file in Gzipstream it can be opened with any popular compression applications such as winzip/ winrar, 7zip but you can't open compressed file with DeflatStream. NET first you can use Gzipstream class and DeflatStream both can actually do compress your files in. There are 2 ways to compress/decompress in. Here is a gist of the full file with some comments. Public static void ExtractTar(string filename, string outputDir) Using (var gzip = new GZipStream(stream, CompressionMode.Decompress)) A GZipStream is not seekable, so copy it first to a MemoryStream Public static void ExtractTarGz(Stream stream, string outputDir) Using (var stream = File.OpenRead(filename)) public static void ExtractTarGz(string filename, string outputDir) Using (var str = File.Open(output, FileMode.OpenOrCreate, FileAccess.Write))Īnd here is a few helper functions for opening from a file, and automating first decompressing a tar.gz file/stream before extracting. If (!Directory.Exists(Path.GetDirectoryName(output)))ĭirectory.CreateDirectory(Path.GetDirectoryName(output)) Var output = Path.Combine(outputDir, name) The primary method is this: public static void ExtractTar(Stream stream, string outputDir) I made a very rudimentary, down-and-dirty method to extract a tar archive to a directory, and added some helper functions for opening from a stream or filename, and decompressing the gz file first using built-in functions. Using those two values, we need only seek to the appropriate position in the stream and copy the bytes to a file. The first is the name, and the second is size. Having looked at the spec for the tar format, there are only really 2 values (especially on Windows) we need to pick out from the header in order to extract the file from a stream. NET conveniently has built-in, which takes care of all the hard part. There is no compression, that is typically handled by compressing the created file to a gz archive, which. At its core, it just takes a bunch of files, prepends a 500 byte header (but takes 512 bytes) to each describing the file, and writes them all to single archive on a 512 byte alignment. While the gz format could be considered rather complicated, tar on the other hand is quite simple. While looking for a quick answer to the same question, I came across this thread, and was not entirely satisfied with the current answers, as they all point to using third-party dependencies to much larger libraries, all just to achieve simple extraction of a tar.gz file to disk.
