im not a pro, but this should work....
first delete all your (static) categorie-folder on the server...
then go to you admin -> setup -> build settings
change
build index to -> index.php
build_extension to -> .php
now youre extensions ar *.php and you can
<?php
include ("your_files.html");
?>
open your categories.html in the editor and include your files...->build all ->
now your include should apear in all categories.
sorry for my bad english !
