Renaming multiple files in Windows XP is supported by Windows XP it self. Don’t look for any free utility or software for renaming multiple files. Windows Explorer makes renaming multiple files very easy. You can also use windows command prompt to rename multiple files.
First, select the group of files that you want to rename. Next, right-click the first files in the group and choose the Rename command from the shortcut menu. Then simply type in a new name. As you do, you’ll need to append the number 1 in parenthesis to the end of the filename. When you press [Enter], each of the selected files will be renamed with the new name, and the number in the parenthesis will be sequentially incremented, as shown in.

It’s Great,i checke its working fine.
