This trick may come in handy when working with large number of similar files. For example When you download photos from your digital camera, file names are usually assigned by camera which are quite unintelligible (however some cameras allow you to change filenames). Whatever be the purpose using this technique you can rename several similar files at one go without editing name of each file manually. This works for all types of files. 1. Open the folder containing files that you want to rename. 2. Select the files you want to rename. If the files you want are not adjacent in the file list, press and hold CTRL, and then click each item to select it. 3. On the File menu, click Rename or press F2. 4.Type the new filename, and then press ENTER. You are done. All of the files in the series will be named in sequence using the new name you type. For example, if you type Birthday, the first will be named Birthday and subsequent files in the series will be named Birthday (1), Birthday (2), and so on..... To specify the starting number for the series, type the starting number in parentheses after the new file name. The files in the series will be numbered in sequence starting with the number you type. For example, if you type Birthday (10), the other files will be named Birthday (11), Birthday (12), and so on.
