I recently ran across a nifty little <$30 utility that, in the right situation, you just might find invaluable. 
Professional Renamer, from Miklsoft, helps catalog images, music and other content of your hard drive via more meaningful file names. The program offers templates and filtering to save time and maintain consistency of name patterns.
The template system allows application of different name patterns to every file type. A name pattern can include up several (up to nine) fields with user-set separators in between. Each field in turn carries a variety of attributes --- such as source name, date, time, counter, user string etc. The attributes are set through dialogs. For instance, time can form a part of a name string.
The program's interface includes a three-panel window which allows movement through system folders,
editing templates, and changes to file names at the same time.
Certainly not something you'll use every day --- but if your stash of digital photos is out of control this might be a good starting point for a "do-over". One CPA told me he intended to use Professional Renamer to re-organize his PDF files.
No endorsement here as the company is Russian. Consider this just information.
