Batch Renaming Tool for Windows 7: A Simple Solution

In this article, we will explore the process of creating a simple tool that can batch rename files in a folder on your Windows 7 system. With the help of Python programming language and its built-in libraries, we will create a script that can easily rename files based on their original names with added zeros to pad the numbers.

The problem we are trying to solve is quite common: you have a folder containing multiple files named as 'file01.txt', 'file02.txt', ..., but you want to rename them to 'file0001.txt', 'file0002.txt', ..., so that they can be easily sorted and managed. To achieve this, we will use the os library in Python to interact with the file system and perform the renaming operation.

The script starts by asking the user to input the path of the folder where the files are located:

```

folder_path = os.listdir(raw_input('Insert folder path: '))

```

This line uses the `os` library's `listdir()` function to list all the files and directories in the specified folder. The `raw_input()` function is used to prompt the user for input.

Next, we define a function that takes a file name as an argument and returns the new name with the added zeros:

```

def rename_file(file_name):

original_name, ext = os.path.splitext(file_name)

number = mysplit(original_name)'1'

add_zero = number.rjust(4, '0')

return original_name + add_zero + ext

```

This function uses the `os` library's `path` module to split the file name into its original name and extension. It then uses a regular expression (regex) pattern to extract the numerical part of the original name, adds zeros to pad it to four digits, and finally returns the new file name with the added zeros.

Now, we can use this function in a loop to rename all the files in the folder:

```

for file_name in folder_path:

new_name = rename_file(file_name)

os.rename(os.path.join(folder_path, file_name), os.path.join(folder_path, new_name))

```

This loop iterates over each file name in the folder path and applies the `rename_file()` function to generate a new name. It then uses the `os` library's `rename()` function to rename the file.

In summary, this script is designed to batch rename files in a Windows 7 system by adding zeros to pad the numbers in their original names. The script prompts the user for input, iterates over each file name in the specified folder, and renames them using the `os` library's built-in functions.
