How to determine the first file of a split archive, in general You want to return true if you don't want to stop a while read loop. If ((header.Flags & 0x01) != 0) return true If (((header.Flags & 0x01) != 0) & currentFile != null)ĬurrentFile.ContinuedFromPrevious = true Do note that if you list the new files, you need to modify this statement in ReadHeader(): // Determine if new file The next file will be the exact same filename and will extract successfully (assuming the file in part 2 isn't corrupted). If (!ntinuedOnNext) throw new IOException("File CRC Error")

Same thing for File Open Error if you opened in read mode. If you are using the C# example from Unrar, you should remove the IOException("File CRC Error") in ProcessFileError() or throw the error.

how to handle unrar.ReadHeader() to proceed with the next file of a split archive.

But I just found my solution and am willing to share. I came across this issue hoping for an answer to all my problems. Marshal.WriteByte(p1, newVolume.Length, (byte)0) Marshal.WriteByte(p1, i, (byte)newVolume) If ((VolumeMessage)p2=VolumeMessage.Notify)Įlse if((VolumeMessage)p2=VolumeMessage.Ask) If ((CallbackMessages)msg = CallbackMessages.VolumeChange) To fix it change: private enum CallbackMessages : uintĪnd handle the new callback message for VolumeChangeW: private int RARCallback(uint msg, int UserData, IntPtr p1, int p2)

The c# wrapper and example included in the unrardll is outdated and does not work well with multivolume rar files because there are new callback messaged that are not handled.
