 ## How does the self-extracting ZIP format work?
-The self-extracting ZIP files created by SingleFile are essentially regular ZIP files. They take advantage of the flexibility in the ZIP specification, which allows for additional data to be included before and after the ZIP payload. In the case of SingleFile, this feature is used to make the ZIP file appear as an HTML file. In this way, the data before the ZIP payload represents the start of an HTML file, and the data after the payload represents the end of this HTML file. The resulting HTML page is technically invalid because it contains binary data (i.e. the ZIP payload), but it's within the bounds of the HTML specification to allow for such cases.

Within this HTML page, there is also a script weighting approximately 50KB designed to extract and display the ZIP payload when the file is opened in a web browser and interpreted as a web page.
 
-By default the ZIP payload is wrapped by `<!--` and `-->` tags. However, if the payload contains the closing tag `-->`, then it is wrapped in another pairs of tags (i.e. tags of `noscript` or `script` or `xmp` or `plaintext` elements) whose closing tag does not conflict with the payload.

 The purpose of the embedded script is to read the ZIP payload as binary data, extract it, and then display the extracted page with its resources. Initially, the script can use the `window.fetch()` method to read the HTML page in binary form and retrieve the ZIP payload. However, this API doesn't work in Chromium-based and WebKit-based browsers when the page is accessed from the local file system due to security restrictions. To circumvent this, the page is encoded in `windows-1251`, and binary data is directly retrieved from the Document Object Model (DOM) when using the "universal" self-extracting ZIP format. The choice of `windows-1251` encoding is preferred over `UTF-8` because it preserves all bytes without significant data loss.
