Can I upload .exe files for LLM to analyze?

[kinwaicheuk-sony]

I have a legacy software installer in .exe format written for Windows XP.

I wonder if I can upload it to the chat for the LLM to analyze it.
When I try to upload it, I got

File type not allowed: application/vnd.microsoft.portable-executable

What should I do?

A direct EXE is usually just machine code with some headers and resources so difficult for most models to understand anyway. The platform blocks executables due to some very valid security concerns if there is malicious stuff encoded in it.

I'm unsure what you mean by analyse, but the best next steps if this is necessary would be to:

• Provide a text representation of the exe -> Hash, pefile headers, etc.

• Or use a disassembly tool e.g. https://github.com/nationalsecurityagency/ghidra

• And then upload those for analysis.

• Alternatively use an online analysis tool such as VirusTotal (but be mindful of privacy and security with these)

I see. Thank you for the detail reply.
Because we can upload .exe files to Claude, and it can tell us how things are implemented and the functions it called inside the .exe file.

So I guess Claude is scanning pefile headers of the exe behind the scene?

I am not scanning for Virus, but just curious about if local LLM can also accept .exe files as Claude do
