Batch renaming files in DOS can be a time-saving and efficient task if done correctly. By utilizing the command prompt, you can quickly rename multiple files with just a few simple commands. First, navigate to the directory where your files are located using the 'cd' command. Once in the correct directory, you can use the 'ren' command followed by the current file name and the desired new file name. Additionally, you can use wildcard characters like '*' to rename multiple files at once. For example, to rename all .txt files in the directory to have a prefix of 'new_', you can use the command 'ren *.txt new_*.txt'. This allows you to rename files in bulk without having to manually rename each file individually. With a basic understanding of DOS commands, you can efficiently manage and organize your files with ease.
