GitHub PR Zipper is a Chrome extension developed by LN Webworks Pvt Ltd. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This free extension is designed to simplify the process of downloading all the changed files in a pull request (PR) on GitHub.

When activated, GitHub PR Zipper adds a new button labeled "Download all changed files" to the GitHub website. This button appears on the web page that is displayed after clicking on a specific pull request. By clicking on this button, users are able to download all the changed files in that pull request as a single zip file.

To use this extension, users first need to provide a Personal Access Token (PAT), as mentioned in the readme file and the graphical user interface of the dialog boxes. Once the PAT is provided, users can simply click on the "Download all changed files" button, and all the files in the pull request will be downloaded to their system. The downloaded zip file maintains the same file system pattern or folder pattern as the files in the repository of the pull request.

GitHub PR Zipper offers a convenient solution for users who frequently work with pull requests on GitHub. Instead of manually downloading each file one by one, this extension allows users to quickly and easily download all the changed files in a pull request with just one click.
