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. 7z file which is password encrypted _unzip : src : C:\Downloads\ApplicationLogs.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. name : Recursively decompress GZ files in ApplicationLogs.zip _unzip : src : C:\Downloads\ApplicationLogs.zip dest : C:\Application\Logs recurse : yes delete_archive : yes - name : Install PSCX _psmodule : name : Pscx state : present - name : Unzip. gz files and removes all unneeded compressed files after completion. zip file, recursively decompresses the contained. # This unzips a library that was downloaded with win_get_url, and removes the file after extraction # $ ansible -i hosts -m win_unzip -a "src=C:\LibraryToUnzip.zip dest=C:\Lib remove=yes" all - name : Unzip a bz2 (BZip) file _unzip : src : C:\Users\Phil\Logs.bz2 dest : C:\Users\Phil\OldLogs creates : C:\Users\Phil\OldLogs - name : Unzip gz log _unzip : src : C:\Logs\application-error-logs.gz dest : C:\ExtractedLogs\application-error-logs # Unzip.
