Problems with rebex sftp file deletion

Question

I'm get a SftpException: No such file; File not found. when using Rebex sftp's Sftp.DeleteFile(string filename) which is especially odd because I'm first checking that the file exists.

Here's the relevant sample code:

foreach (var file in fileList)
{
    if(ftp.Connection.FileExists(file.Name))
    {
        try
        {
            ftp.Connection.DeleteFile(file.Name);
        }
        catch (SftpException ex)
        {
            Log.Error("Deletion failed.", ex);
        }
    } 
    else
    {
         Log.Debug(string.Format("'{0}' not found.", file.Name));
    }
}

Rebex's online docs can be found here for those not familiar with the library.

Any ideas as to what's going on here?

Usually the library just translates server's error message. Did you try with Rebex support (they are responsive)? — Eugene Mayevski 'Callback, Jul 28 '11 at 16:15

David also asked this question on our support forum at http://forum.rebex.net/questions/1635/sftpexception-no-such-file-file-not-found

I'm recording the solution here too, because it can be handy in similar situations.

The file does exists on the SFTP server
Application opens a stream which locks the file on server
The file cannot be deleted and server reports "No such file; File not found." error message
Closing those streams resolves the issue and file can be deleted now.

Unfortunately the SFTP server error message was not very helpful in this case. One could ask if something like "access denied" would not be more appropriate.
