Windows XP has a feature that allows you to rename several files at once. For instance, pictures you've recently taken from your digital camera are usually named with sequential non-descriptive numbers. To rename the whole batch of pictures, click Start, and then click My Pictures or whichever folder contains the files you'd like to rename. Open the folder, click View from the toolbar, and then select Thumbnails. Now you can see a thumbnail of the image you are considering renaming. Select all the pictures you want to rename with your mouse (hold left mouse button and drag), or select the first picture you want to change and hold the SHIFT key and use the arrows to select the pictures you want to rename. Right-click the first picture, and then click Rename. Type a new name that is descriptive of all the pictures you've selected, and then deselect the pictures by clicking in the white space next to one of the pictures. Now all of the pictures are named in sequence. This tip can also be used to rename a batch of any files, not just picture files.
