OTTObatcher Description:

OTTObatcher allows the selection of any number of files within a folder and quickly rename them with a common prefix plus an auto-generated sequence number. Quickly and easily rename your digital photos with a topic and/or date designation. The program allows you to overwrite existing files, but protects against accidental overwriting. The interface provides either a checklist format or standard Windows list with multi-select capability and thumbnail preview for many image types.

Trial download available at ottomatick.com; OTTObatcher is fully functional for a 30-day trail period, after which you are limited to selection of 10 files at a time.
