on delete -> files

Hello. I'd like doctrine could map a column with a directory in order to put in that column a name of a file and when that row were deleted, the file going to be deleted. For example, if I have a table with the names of images, and a customer with a foreign key to an image, when I delete the costumer with cascade, the image row will be deleted. It would be a great idea if a file named like the name in that table were deleted too. So, we don't need to delete the file manually and we don't need to store the binary file into the database.

I hope my explanation were clear. Sorry for my English
