Hi! Maybe the problem is the value of your variable "toPath";

set it like this...

string toPath = @"C:\SubDirectory";

the value of the path is the backupfolder og UNC path to a directory set by user in application as settings.....
and it is declared like this:  string toPath = myFileTypeSettings.BackupPath;

i was in a meeting so i wil try to set Directory.Exists method instead of DirectoryInfo to se if it works...?!

here is the full method/function:
   private void BackupImportedFiles()
        {
 
            if (myFileTypeSettings.BackupPath.Trim() != "" && toolStripMenuItemMoveFilesToBackup.Checked)
            {
                foreach (SimpleFile objFile in arrayImportFiles)
                {
                    String fileName = objFile.FileName;
                    string toPath = myFileTypeSettings.BackupPath;
                    DateTime now = System.DateTime.Now;
                    string date = now.ToString();
                    int startpos = fileName.LastIndexOf("\\") + 1;
                    int lengde = toPath.Trim().Length;
                    // Adds \ at the end of the backup path it not exists)
                    if (toPath.Substring(lengde) != "\\")
                    {
                        toPath += "\\";
                    }
 
                    date = date.Replace(" ", "_");
                    date = date.Replace(System.Globalization.DateTimeFormatInfo.CurrentInfo.TimeSeparator, "");
                    date = date.Replace(System.Globalization.DateTimeFormatInfo.CurrentInfo.DateSeparator, "");
                    toPath += date + " " + fileName.Substring(startpos);
 
                    FileInfo file = new FileInfo(fileName);
 
 
                    if ((file.Attributes & FileAttributes.ReadOnly) != FileAttributes.ReadOnly)
                    {
                        DirectoryInfo dirPath = new System.IO.DirectoryInfo(toPath);
 
                        if (dirPath.Exists == true)
                        {
                            file.MoveTo(toPath);
                        }
                        else
                        {
                            MessageBox.Show(GetValue("couldntMoveFile") + fileName + GetValue("madeacopyinstead"), GetValue("warning"), MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
                            file.CopyTo(toPath);
                            return;
                        }

                        {
                            file.MoveTo(toPath);
                        }
                        else
                        {
                            MessageBox.Show(GetValue("couldntMoveFile") + fileName + GetValue("madeacopyinstead"), GetValue("warning"), MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
                            file.CopyTo(toPath);
                        }
