Copy file fo mapped network drive using FileInfo.CopyTo

I try to copy a file to a mapped network drive, but I always get the message "Could not find a part of the path ...". I tried different mapped network drives, so I could exclude credential problems (it neither works with a drive connexcted with different credentials nor with my normal user)

  try
  {
     fi.CopyTo(SystemReg.TargetPath + fi.Name);
  }
  catch (Exception e)
  {
        SystemReg.Log.AppendLine("Copy failed! " + Environment.NewLine + e.Message);
  }

SystemReg.TargetPath is read from an XML file. If I use a local path like D:\temp\ it works perfectly, but e.g. X:\temp\ with X as a mapped drive it fails.

I also tried to run my program in a batch file with "net use..." before calling my program, it also fails.

Solution

  • You shoud use computer address instead of drive name.

    For example, if your computer's address is 192.168.0.200 which keeps shared folder temp\ then your full path is \\192.168.0.200\temp\
