.txt.txt -

The "Save As" dialogue MUST prompt the user to normalize the file to a single .txt extension.

The system MUST flag .txt.txt files in email attachments or download folders for potential spoofing. 3. Implementation Logic Detection: Scan for file extension regex: ^.*\.txt\.txt$ Handling Rule:

This document outlines a functional specification for implementing a robust double-extension .txt.txt handler, designed to safely manage scenarios where text files are inadvertently saved with dual extensions, preventing common data loss or security issues. Feature Specification: .txt.txt Extension Handler Draft Version: 1.0 1. Purpose .txt.txt

is this for (Windows, macOS, or a custom app)? Knowing this will help me refine the code or steps!

When a user attempts to save a file as .txt.txt , a warning should appear stating: "The extension '.txt.txt' is unusual. Did you mean '.txt'?" This helps prevent user confusion. To make this feature even better, let me know: The "Save As" dialogue MUST prompt the user

Default text editors (e.g., Notepad, TextEdit) SHOULD open .txt.txt files directly.

The purpose of this feature is to identify, validate, and correctly process files named with the suffix .txt.txt (e.g., report.txt.txt ). It ensures that applications treating these as plain text still parse them correctly, while security systems recognize them as potentially deceptive. 2. Functional Requirements Knowing this will help me refine the code or steps

if filename.endswith(".txt.txt"): safe_filename = filename.replace(".txt.txt", ".txt") # Log incident for user warn_user("Double extension detected. Renaming for safety.") Use code with caution. Copied to clipboard
