How to rename multiple files or pictures all at once
If you are one of those poeple using a Digital camera to capture pictures, when you import your pictures to your computer, chances are that you have a wierd naming scheme such as DSC001021 something etc. Using this tip, you would be able to rename many pictures all at once.

1. Open the folder where you have saved your pictures. Select the batch of pictures you wish to rename. You can select multiple pictures by pressing <Ctrl> key plus the picture. Do not let go of the <Ctrl> key when you select a different picture.
2. Right-click the first picture selected and then click Rename.
3. Rename the first picture to whatever you like (for example, Vint Cerf Google Speaker Series), then click any empty space within the window to deselect the pictures.
Your pictures automatically rename themselves (”Vint Cerf Google Speaker Series (1),” “Vint Cerf Google Speaker Series (2),” etc.). This tip also works to rename any collection of files.
