Problem to read the next file

Question

Guys, good afternoon! I am having trouble reading the files in a directory, it presents an error as if it were going the wrong way, but I do not see this fault, could someone guide me?

Here is where I check the file extension and inform the path:

public static class ReadingTxt
    {
        static Thread _ThreadVerification;

        static string PendingFiles =@"D:\Pendrive\PENDENTS";
        static string FileFilesImported = @"D:\Pendrive\IMPORTED";

        static string FolderLogLog = @"D:\Pendrive\LogImportProvider";

        public static void Read ()
        {
            // creation of the verification thread and its execution
            _ThreadVerification = new Thread;
            _ThreadVerification.Start ();
        }

        // will check whether or not to execute the method every 1 hour
        private static void CheckTime ()
        {
            while (true)
            {
                if (DateTime.Now.Hour == 16) // If it is 07:00 AM in the morning
                {
                    InsertLog ("");
                    InsertLog ("\ n HOME ::" + DateTime.Now.ToShortDateString () + "" + DateTime.Now.ToShortTimeString ());

         try
                    {
                        DirectoryInfo dirPending = new DirectoryInfo (PendingPlacesFolder);

                        // list files in the current directory
                        foreach (FileInfo file in dirPending.GetFiles ())
                        {
                            if (file.Extension == ".cpv")
                            {
                                Process File (file.FullName, file.Name);
                            }
                        }

                    }
                    catch (Exception)
                    {
                        throw;
                    }
                    finally
                    {
                        InsertLog ("\ n FIM ::" + DateTime.Now.ToShortDateString () + "" + DateTime.Now.ToShortTimeString ());
                    }
                }

                Thread.Sleep (3600000); // 3,600,000 milliseconds equals 1 hour (Standby)
            }
        }
}

Method to move the file:

private static void MoveFile (string FileName)
        {
            try
            {
                FileFilesImported + = "\\" + FileName;
                FileFilespendents + = "\\" + FileName;
                File.Move (FolderFiles, FileFilesImported);
            }
            catch (Exception)
            {
                throw;
            }

        }

Method of inserting the log:

private static void InsertLog (string row)
        {
            // Create Log Folder, if it does not exist
            if (! Directory.Exists (LogFileLog))
            {
                Directory.CreateDirectory (LogFileLog);
            }

            // Create Log File, if it does not exist
            string FullPath = LogFileLog + "\\ LogTexto.txt";
            if (! File.Exists (FullPath))
            {
                using (File.Create (FullPath));
            }

            // Write to LOG file
            using (StreamWriter file = new StreamWriter (FullPath, true))
            {
                file.WriteLine (line);
                file.Dispose ();
            }
        }

Error: System.IO.FileNotFoundException: 'Could not find the file' D:\Pendrive\PENDENTES\CGc0001.cpv\CGc0360.cpv '.' This happens every time I read the next file.
