What is a Batch Script?
A batch script is a text file containing a series of commands that are executed by the command interpreter on Windows operating systems. Batch scripts are incredibly useful for automating repetitive tasks, such as renaming files.
Renaming All Files Sequentially
Let's say you have a directory full of files that you want to rename. You want the new names to be sequential numbers, starting from 0. Here's how you can do it with a batch script:
@echo off
setlocal EnableDelayedExpansion
set i=0
for %%A in (*) do (
ren "%%A" "!i!%%~xA"
set /a i+=1
)
This script will rename all files in the current directory to numbers from 0 to 9, preserving their original file extensions.
How Does the Script Work?
Here's a breakdown of what each line in the script does:
@echo off: This line prevents the commands in the script from being printed to the console.setlocal EnableDelayedExpansion: This line enables the use of delayed variable expansion, which allows us to use the !i! syntax to access the value of i inside the loop.set i=0: This line initializes the variable i to 0.for %%A in (*) do: This line starts a loop that iterates over all files in the current directory.ren "%%A" "!i!%%~xA": This line renames the current file (%%A) to the current value of i, followed by the original file extension (%%~xA).set /a i+=1: This line increments i by 1.
Running the Script
To run this script, save it as a .bat file in the same directory as your images, then double-click the .bat file to execute it.
Important Notes
Please make sure to backup your files before running this script as it will overwrite existing files without warning. Also, this script assumes that there are exactly 10 files in the directory. If there are more or less, you may need to adjust the script accordingly.
Moreover, be aware that this will rename all files in the directory, not just image files. If you want to rename files of a specific type, you can replace (*) with (*.filetype), where filetype is the extension of the files you want to rename.
