How to manually modify the zip.html file?

[onoter]

Just wanted to manually modify a saved zip.html file. I tried to unzip it, modify, and re-zip. But the file can't be opened correctly, only showing random characters.

I'm curious what this 'self-extracting zip file' is. The only 'self-extracting zip file' I know is exe file on windows, which is certainly not the case.

And most importantly, how to re-zip it manually?

I think you need to make your changes, then just open index.html and save rendered page with SingleFileZ.
