This tool is designed for file extension spoofing. It allows users to create a copy of a file with a spoofed extension. This can be useful in various testing scenarios, including security testing and penetration testing exercises. The tool uses a special Unicode character to reverse the order of characters in the spoofed extension.

IMPORTANT: This tool is intended for educational purposes and legal ethical testing only. Misuse of this tool for deceptive or malicious purposes is strictly prohibited.
