You can manually search the file tree ignoring system directories.

// Create a stack of the directories to be processed.
Stack dirstack = new Stack();
// Add your initial directory to the stack.
dirstack.Push(new DirectoryInfo(@"D:\");

// While there are directories on the stack to be processed...
while (dirstack.Count > 0)
{
    // Set the current directory and remove it from the stack.
    DirectoryInfo current = dirstack.Pop();

    // Get all the directories in the current directory.
    foreach (DirectoryInfo d in current.GetDirectories())
    {
        // Only add a directory to the stack if it is not a system directory.
        if ((d.Attributes & FileAttributes.System) != FileAttributes.System)
        {
            dirstack.Push(d);
        }
    }

    // Get all the files in the current directory.
    foreach (FileInfo f in current.GetFiles())
    {
        // Do whatever you want with the files here.
    }
}
