The only way I know to change the file name on the SX series is using the software that came with the camera when you are downloading to the computer. Even the high end G series cameras only allow you to change the way the numbering is done, either continuously or auto-reset. There may be a way with CHDK software, but I haven't used that on my cameras to know enough about it.

Thanks for the reply Smack53. I can't believe a major company like Canon would produce something so restrictive. I am getting around the problem using a file renaming feature on a product called Total Commander; but is a convulted process.

The DPP (Digital Photo Professional) software that comes with the camera has an excellent renaming tool that makes the task very simple. You can rename one, some, or all photos at one time. This is the tool that Canon uses for all their cameras for basic editing, trimming, cloning, etc. If you haven't used it, why not give it a try. You can even rate your photos and look at the shooting information (EXIF). Best part is its free software.
