How do people handle file naming? Cameras I've seen have different file name schemas. Some are date related. Some just seem to be an incrementing value. When I save my files I often want a topic related name. If I have 10s or 100s of them then naming them can be a daunting task. Is there a tool that can do easy renaming of bulk files? Being a software developer I have a little perl script I use but it isn't all too user friendly for others to use. What else is available? If nothing then I'll consider making a renaming tool and make it freely available.
