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

Ensure File Open Dialogues include *.txt.txt in the "Plain Text Files" filter. 4. User Experience

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

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: Default text editors (e

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

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 The system MUST flag

The system MUST identify files ending in .txt.txt as plain text files, similar to .txt files.
