Please check the below code for the solution.
public static bool IsLocked(this FileInfo f)
{
    try
    {
        string fpath = f.FullName;
        FileStream fs = File.OpenWrite(fpath);
        fs.Close();
        return false;
    }

    catch (Exception) { return true; }
}

FileInfo fi = new FileInfo(@"C:\4067918.TIF");
if (fi.IsLocked())
{
   var sourceFile = new FileInfo(sourceFilePath);
   sourceFile.CopyTo(destFilePath, true);
}

It depends on Windows when you open a file the file is locked by the OS, which means you can't open it as only one process should have access to it. Some applications open the file, read it and then close it, which would allow you to open the same file but it an OS limitation and programming can't help much in that matter.
