  Hello!
  
  I want to check the name of each file in the zip file but unfortunately the files with Japanese names are corrupted. Is there any way to fix it?

  i use C1.WPF.Zip.4.6.2

  Hi,

  You can set the encoding option to ANSII/OEM - Japanese Shift-JIS (932) to get the desired behavior. Here is the code snippet for the same:

  ZipEncoding.Encoding = Encoding.GetEncoding(932);
  C1ZipFile zip = new C1ZipFile();
  zip.Open(path);

  We have attached the updated sample for full implementation. [ConsoleApp7_Upd.zip]

  Thanks & Regards,

  Hi,

  This exception shows that the password was entered incorrectly.

  As per the developers, this is because C1.Zip supports only CRC32 Encryption at the moment. Password encrypted in AES-256 is not supported.

  We highly apologize for the convenience caused but this is a limitation as of now.

  Thanks & Regards,
