Batch Rename PDF Files in a Directory using PowerShell

This PowerShell script is designed to batch rename PDF files within a specified directory. It first sets the directory path and the desired file extension (.pdf). Then, it retrieves all files within the directory and iterates through each file, appending the specified extension to the original file name. Finally, it renames each file with the new name, effectively converting them to PDF files. This script provides a convenient solution for renaming multiple files at once, streamlining file management tasks with ease.
