:: CompressAndEncryptFiles version 2.1
:: A batch script to compress and encrypt files in a directory and its subdirectories using a RAM disk.
:: Each file is archived individually in the specified output directory or the original directory.
:: This script uses 7-Zip for compression and encryption with AES-256.
:: Author: ChatGPT (OpenAI)

:: Source: https://github.com/oood/CompressAndEncryptFiles

:: Set the path to 7z if it's not in the system's PATH
