Introduction

Windows 11's commitment to enhancing user experience has led to continuous improvements in system performance. A notable area of focus has been the optimization of archive extraction processes within File Explorer. This article delves into the advancements made, the challenges that persist, and the overall impact on users.

Background

Archive files, such as ZIP, RAR, and 7Z, are integral to file management, enabling efficient storage and transfer of data. Historically, Windows' native support for these formats has lagged behind third-party tools like 7-Zip and WinRAR in terms of speed and functionality. Recognizing this, Microsoft has undertaken efforts to bridge the performance gap.

Recent Developments
