Cable Forum - Batch rename

Windows XP has a little-known facility for renaming and numbering files in batches. The first step is to highlight all of the files you want to change. You can do this individually by holding down the Ctrl key and clicking each one in turn, or if there are a lot of them, hold down the Shift key and use cursor arrow down or the Page Down keys to speed up the operation. Next, right-click the first file in the block and select Rename. Enter the new file name, hit Return and all of the highlighted the files will be automatically renamed and numbered. If you want to specify the start number then enter the number you want to start at in brackets, so in your case the first file would look something like this: 'mypicture(51).jpg and all subsequent files will be numbered in sequence.
