delete specific jpg files from folders and subfolders using Excel VBA

Dear Experts:

I understand that it is possible to delete files from a folder using Excel VBA

I am running Excel 2010 on Windows 7

I would like to delete specific jpg files from a directory with many folders and subfolders. The directory's name is ...
... C\Graphics\...

The jpg files that are to be deleted are only those that have the following characters at the end:

_h.jpg or _n.jpg, i.e. for example 90-147-58-30_h.jpg or 94-111-24-39_n.jpg. All other jpg files that do not match these criteria are not to be touched.

Help is very much appreciated. Thank you very much in advance.

Kind regards, Andreas
