How to send mail notification after each file has processed?

Hello all,

i have to send a notification after each file has been processed.

For example i have two files named "mail_details1" and "mail_details2".After each file is processed a notification has to sent. Total 2 notifications has to be sent .This is working when two files have different names like "mail_details1" and "mail_details2".

But i have a problem where two files names are same like

"mail_details1" and "mail_details1". Here im getting only one notification.

Can anybody help me out please what's happening here.
