Drupal 7 - can't see my module

If you can't see your Module in Drupal 7 here's the very basics that's needed.  Check these things are in place and you should be able to see your module.

Create a new folder in your installation

Sites/All/Modules/Custom/helloworld

Create 2 files

helloworld.info
helloworld.module

in helloworld.info

name = "Hello World"
description = "Hello Modules list !."
core = 7.x


files[] = helloworld.module

helloworld.module  can be blank.  And thats it.  Make sure you clear your cache in admin.
