Surprisingly, the RENAME (aka REN) command in DOS supports wildcards.
If you had a stack of files called:
- DSC_0001.JPG
- DSC_0002.JPG
- DSC_0003.JPG
- DSC_0004.JPG
You could call:
REN DSC_*.JPG Photo_*.jpg
And it'll replace the text accordingly like:
- Photo_0001.jpg
- Photo_0002.jpg
- Photo_0003.jpg
- Photo_0004.jpg
What's even more surprising is that this solution came from Yahoo answers!
