Then use WinRAR.

For the rest of us, this is expected behaviour, and I don't want 7z special-casing exes or always extracting all files in an archive just to open one.

It could always be a setting. Feels like yet another situation where OSS prioritises principles over usability/practicality/reality.

If I want to open the README in a multi-gigabyte archive, why would I expect to extract all of it, even as a setting?

This seems the expected and reasonable behavior to me, as a second data point.

Because of the behaviour I detailed in my initial post? Wouldn't apply to ReadMe's though, it doesn't have to be that dumb. At least one other poster agrees with me in the comments too.

Aren't all extension special cased anyway?
