editing photo names

[4rgrstvr]

I have several thousand photos and I need to edit the names with some system that uses my time efficiently. In the past I used windows explorer, which allowed me to modify groups of titles but now I just updated to windows 7 and it does not seem to allow that. Is there some way with Paint Shop Pro to modify the names of groups of photos - extract certain characters or words, add other characters or words, etc?

Or perhaps there is a photo organizing program that provides that kind of tool?

PSP does have a batch rename option.

With this option you can use Custom Text - The image date - file name - the sequence of the batch - and the time.

If you need something more powerful it's also possible, if you wanted something more powerful, to program a script to do it. But chances are you don't want to get into programming. xD

From there I'm of no help. I don't use photo managers.

Try Irfanview. Free, efficient, can use wildcards (#) to represent numbers, can take out a common part and replace with another part without main numbers being changed. ( festx replace with fest ---and have festx002, festx005, festx009 go to fest002 , fest005, fest009), renumber by 2 or 3 or whatever . Very versatile.
