This MSDN site has an example to gzip a file. Then, how can I gzip a whole directory with sub directories in it?

Since gzip only works on files, I suggest you tar your directory and then gzip the generated tar file.

You can use tar-cs or SharpZipLib to generate your tar file.

The magic number in GZip header is not correct. Make sure you are , Since gzip only works on files, I suggest you tar your directory and then gzip the generated tar file. You can use tar-cs or SharpZipLib to generate your tar file. first of all thank you very much about your code it is very helpful for me.indeed i have to develop windows application .net 2.5.your code works fine with compress folder and its containing files.but when decompress it decompress first file well and throw exception SystemOutOfMemory because of

You can't !

GZip was created for file, not directories :)

How to compress/decompress directories using GZipStream , Make sure you are passing in a GZip stream.(.exe file) - c#. Gzip a directory that has subdirectories using GZipStream class with C#?. This MSDN site has an � To decompress a file, use the same the GZipStream class. Set the following parameters: source file and the name of the output file. From the source zip file, open a GZipStream. using (var zip = new GZipStream(inStream, CompressionMode.Decompress, true)) To decompress, use a loop and read as long as you have data in the stream.

gzip operates on a simgle stream. To create a multi-stream (multi-file) archive using the gzipstream you need to include your own index. Basicly, at its simplest you would write the file offsets to the beginning of the output stream and then when you read it back in you know where the boundaries are. This method would not be PKZIP compatible. To be compatible you would have to read and implement the ZIP format... or use something like SharpZip, or Zip.NET

How to: Compress and extract files, How to compress/decompress directories using GZipStream If first parameter is a compressed file, the utility restores all files to the destination directory (second Compression; namespace CmprDir { class Program { delegate void GetBytes (c), 0, sizeof(char)); //Compress file content byte[] bytes = File. The GZipStream is a Decorator on a Stream.It adds GZIP compression or decompression to any stream. Like the System.IO.Compression.GZipStream in the .NET Base Class Library, the Ionic.Zlib.GZipStream can compress while writing, or decompress while reading, but not vice versa.

You can zip the directory in pure .NET 3.0. Using SharpZipLib may not be desirable due to the modified GPL license.

First, you will need a reference to WindowsBase.dll.

This code will open or create a zip file, create a directory inside, and place the file in that directory. If you want to zip a folder, possibly containing sub-directories, you could loop through the files in the directory and call this method for each file. Then, you could depth-first search the sub-directories for files, call the method for each of those and pass in the path to create that hierarchy within the zip file.

public void AddFileToZip(string zipFilename, string fileToAdd, string destDir)
{
    using (Package zip = System.IO.Packaging.Package.Open(zipFilename, FileMode.OpenOrCreate))
    {
        string destFilename = "." + destDir + "\\" + Path.GetFileName(fileToAdd);
        Uri uri = PackUriHelper.CreatePartUri(new Uri(destFilename, UriKind.Relative));
        if (zip.PartExists(uri))
        {
            zip.DeletePart(uri);
        }
        PackagePart part = zip.CreatePart(uri, "", CompressionOption.Normal);

        using (FileStream fileStream = new FileStream(fileToAdd, FileMode.Open, FileAccess.Read))
        {
            using (Stream dest = part.GetStream())
            {
                CopyStream(fileStream, dest);
            }
        }
    }
}

destDir could be an empty string, which would place the file directly in the zip.

GZipStream Class (System.IO.Compression), Compress & extract files using System.IO. GetFullPath(extractPath); // Ensures that the last character on the extraction path // is the directory separator char. zipToOpen = new FileStream(@"c:\users\exampleuser\release.zip", FileMode. You can also use the GZipStream and DeflateStream classes to� The .NET framework provides us a way to compress and decompress data using the classes under the System.IO.Compression. There are two main classes that perform the job, namely the GZipStream class and the DeflateStream class. Both use the same algorithm to compress and decompress data but there are some differences.

Can I zip an entire folder using gzip?, The following example shows how to use the GZipStream class to compress and decompress a directory of files. C# Copy. using System; using System.IO; using� Example of using tar and gzip to compress a folder. Let’s say I have a bunch of files in a directory. If I use the du command to get the size of the directory, it’s 204 KB. du -sh sample_text_files 204K sample_text_files. Now if I gzip compress the folder:

UNIX commands — Compressing directories and files – DreamHost , compress it using the z (gzip) algorithm. c (create) an archive from the files in directory ( tar is recursive by default). v (verbosely) list (on /dev/stderr so it doesn't � The GZipStream class uses the gzip data format, which includes a cyclic redundancy check value for detecting data corruption. The gzip data format uses the same compression algorithm as the DeflateStream class. It seems GZipStream adds some extra data to the output (relative to DeflateStream).

Extract zlib, local computer. All you need to do is log into your server via SSH and run the commands shown below. You can use the 'zip' command to compress a folder full of files. of the file: [server]$ gzip -c test.log > test.log.gz� I am trying to compress JSON files using Gzip compression to be sent to another location. It needs to process 5,000 - 10,000 files daily, and I don't need the compressed version of the file on the local machine (they are actually being transferred to AWS S3 for long-term archiving).

  • Also, see: stackoverflow.com/questions/1001711/…
  • +1. You can however, do something like, say, creating a tarball, and gzip that to get a *.tar.gz file. Or just zip the whole thing with DotNetZip (dotnetzip.codeplex.com)
