When copying over your digital pics to your computer, you might notice some unrecognizable file name, such as DG01, DG02, DG03, and so on. It would be tedious to rename every one of them. 
There is an automatic way in Windows XP to apply a meaningful naming sequence. So, you may name your first baby photos as Baby_1.jpg, Baby_2.jpg, Baby_3.jpg and so on.
Here is how to automate a naming scheme for your pics:
1. First, open the folder and select View > Thumbnails.
2. Click the last picture in the folder you want to rename, hold down the Shift key, and click the first picture; this will select them all.
3. Right-click the first photo, and select Rename from the drop-down menu.
Windows XP will highlight the filename for the first photo, enabling you to give it a descriptive name. After you type in the name, click the white space outside of the photo and watch as Windows applies the name with a sequential number to each picture in the folder.
