I'm sure the file exist, there is no need to create.
With another SFTP lib, i haven't this problem.

Best regards

Hi,

if some of the downloaded files already exist, and you want to overwrite them just use the ActionOnExistingFiles parameter:

var sftp = new Sftp();
sftp.Connect("server");
sftp.Login("user", "password");

sftp.Download("remotePath", "localPath", 0, 0, ActionOnExistingFiles.OverwriteAll);
sftp.Disconnect();

Hello,  i have the same error  with your example.
This problem is not in local to rewrite the file, it's on the remote file.

Thanks

The server does not allow the file to be opened. Are you able to download the file with a third party SFTP client?

---

Yes, I can download the same files with another SFTP client.

---

Could you please try the following code on the problematic file and let me know whether it is able to download the file:

            var client = new Sftp();
            client.Connect("server");
            client.Login("user", "password");

            try
            {
                string remoteFile = "/Label/20160325Format1.prn";
                string localFile = @"C:\temp\20160325Format1.prn";
                bool fileExists = client.FileExists(remoteFile);

                // download the file directly (full path used)
                Console.WriteLine("File exists {0}", fileExists);
                client.GetFile(remoteFile, localFile);
                Console.WriteLine("Download was succesful.");
            }
            catch (SftpException ex)
            {
                Console.WriteLine(ex.ToString());
            }

Hello

I tried your code and i have still the same problem (Error Opening/Creating File), but the file exists.
I forgot to say, i'm on the PDA Windows Mobile.

---

Hello, and thanks!

Could you please post a from the code with FileExists as well?

Also, it might help us a lot if you named the SFTP server you use and the SFTP client that was able to download the file. If we were able to reproduce this behavior, I'm sure we could solve it within hours.
