Hi there!

    Whenever I zip up multiple files of about 0.5MB each, I'm getting bad CRC errors when I try to unzip the resulting Zip file. Below is what I'm basically doing:

ZipOutputStream s = null; 

s = new ZipOutputStream(File.Create(zipName));
            s.SetLevel(0);
            foreach (string file in filenames)
            {
                if(File.Exists(file))
                {
                    FileStream fs = File.OpenRead(file);
                       
                    byte[] buffer = new byte[fs.Length];
                    fs.Read(buffer, 0, buffer.Length);
                       
                    FileInfo fi = new FileInfo(file);
                    ZipEntry entry = new ZipEntry(fi.Name);
                       
                    s.PutNextEntry(entry);
                       
                    s.Write(buffer, 0, buffer.Length);
                    fs.Close();       
                }
            }
                   
            s.Finish();
            s.Close();        

Can someone tell me what is it I'm doing wrong here? 

Hi,

Make sure you have the latest version of the library.

try SetLevel(9).

Tip: Dont allocate a buffer the size of each file each time, its a huge memory overhead.
