Could not determine if file `x` exists

Question

I'm having an issue where I can't check if a file exists on my FTP Server.

This is my code:

if (ftp.Exists(UpdateFileThere)) //exception here
{
    GetFile(UpdateFile, UpdateFileThere);
    FileVersionInfo versionUpdate = FileVersionInfo.GetVersionInfo(UpdateFile);
    Assembly assembly = Assembly.GetExecutingAssembly();
    FileVersionInfo versionRunning = FileVersionInfo.GetVersionInfo(assembly.Location);
    if (versionRunning.FileVersion != versionUpdate.FileVersion)
    {
        InsertLog(1, "Update found. Updating to: " + versionUpdate.FileVersion);
        Process.Start(Updater);
    }
    else
    {
        File.Delete(UpdateFile);
    }
}

Besides this I'm facing another crazy issue, where I can't create a directory because the directory name is prohibited(?)

ftp.CreateDirectory(Path.Combine("Users", UserName, "Logs"));

This line throws an exception saying that the directory name was prohibited.


I have used eftFTPnet before and didn't have those issues. Also, I'm using the same host I've used in the past. I think it may be bugs causing this.

Answer 1

Please post the debug log file.
