I have a directory with 3 kind of files

```
1. thisdir/some/phpfile.php

2. thisdir/some/after-url-rewrite/1 (all numbers)

3. thisdir/something.htm (block any file end with .htm in thisdir/

```

I just want to block the 3rd type of files, since there are not existing any more, but search engine spider keep asking for them

Thanks for your help.
