    I'm writing to say that the particular example:

    using System;
    using System.IO;

    using ICSharpCode.SharpZipLib.Core;
    using ICSharpCode.SharpZipLib.Zip;

    class MainClass
    public static void Main(string[ args)
    string[ filenames = Directory.GetFiles(args[0]);
    byte[ buffer = new byte[4096];

    using ( ZipOutputStream s = new ZipOutputStream(File.Create(args[1])) ) {

    s.SetLevel(9); // 0 - store only to 9 - means best compression

    foreach (string file in filenames) {
    ZipEntry entry = new ZipEntry(file);

    using (FileStream fs = File.OpenRead(file)) {
    StreamUtils.Copy(fs, s, buffer);
    Does NOT work in my case. The problem is that the entries (files) into the ZIP archive appear to be 4G each, and I try to extract I got an error.
    What Solved my problem is adding some extra lines of code:
    FileInfo fi = new FileInfo(file);
    ZipEntry entry = new ZipEntry(fi.Name);
    entry.Size = fi.Length;
    Now everything works just fine.

    Re: ZipEntry.Size


    A well known problem.  Its working fine either way it all depends on what you use to look at the results with.  Setting the size is the best regardless as its the slightly more efficient and provides the broadest compatability.

    Gee ;)

    The result file is being opened with WinRAR 3.51 ... if I do not set the SIZE, no success with WinRAR.
