.txt.txt

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

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

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: is this for (Windows, macOS, or a custom app)

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

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:

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