NameChanger

NameChanger is an application for renaming files that lets you process file lists by the batch and change their titles in different ways. 

Adding characters before or after the original name and substituting certain characters for others are just some of the main things NameChanger can do. 

The program also lets you add a certain date in the format of your choice, set a number sequence to substitute the original name, input mask characters, or delete a certain number or range of characters.

NameChanger can also hide the file extension so it doesn't affect how it opens, ignore capital letters, and force the existence of unique names. That said, if you don't like it you can always use FileList.
