So you have a bunch of photos with stupid names like DSC000393 or IMG293933 right? Not very useful. Trying to rename each one would be a pain also. That’s where File Renamer Basic can help. Using this utility, you can quickly rename a bunch files with lots of options of prefixes, suffixes, or what you like.
This seems like a useful utility. I use Renamer which is another one of these programs. I prefer that because it is portable.
Siren 2.00 is a great utility you can use to rename files based on all sorts of data: http://www.scarabee-software.net/en/siren.html
