When I try to to read the content of the zipped file 562E0101.STM in 562E0101.ZIP I get exception "Bad password".
However, the password is correct. I am able to unpack with it when using WinRar, WinZip, Total Commander (unzip), even SharpZipLib works just fine (I suggest you take a look into their code).
Try to decompress the file attached with 6chars long password: 472713
The code I use:
using (ZipFile zip = ZipFile.Read(filePath))
zip.Password = password;
foreach (ZipEntry e in zip)
string entryName = Path.GetFileName(e.FileName);
string entryNameWithoutExtension = Path.GetFileNameWithoutExtension(entryName);
return Path.Combine(tmpFolder, e.FileName);
