Ex-Microsoft engineer rebuilds Notepad in 2.5KB using nothing but stuff Windows already had

Dave Plummer, a retired Microsoft engineer, has developed TinyRetroPad, a Notepad-like application that is only 2.5 kilobytes in size. TinyRetroPad includes features such as Open, Save, Find and Replace, printing, font selection, word wrap, and an unsaved changes prompt. It is built on existing Windows components, allowing it to function efficiently without extensive resources. TinyRetroPad is based on Dave’s Tiny Editor and utilizes RICHEDIT50W for text handling. The application's file size increased incrementally with each feature added, with the final size being 2,476 bytes. Crinkler, a compression linker, was used to optimize the executable. TinyRetroPad is still in development, facing issues like high memory consumption and compatibility problems. In contrast, Windows 11's Notepad has become larger and more complex, weighing approximately 352KB and incorporating features that some users find unnecessary. Windows 11 LTSC retains the classic Notepad without modern features, while TinyRetroPad aims to demonstrate the potential for simplicity in application design.

Ex-Microsoft engineer rebuilds Notepad in 2.5KB using nothing but stuff Windows already had

Dave Plummer, a former Microsoft engineer, is recreating Notepad in 2.5 kilobytes with a project called TinyRetroPad, which includes features like Open, Save, Find and Replace, printing, font selection, word wrap, and unsaved changes prompt. TinyRetroPad leverages existing Windows infrastructure, utilizing built-in resources to function efficiently. It is based on Matt Power’s Dave’s Tiny Editor and operates as a wrapper around RICHEDIT50W. The size of TinyRetroPad increased with each feature added, reaching 2,476 bytes with printing. The project uses Crinkler, a compression linker, to optimize the executable. TinyRetroPad currently lacks a dedicated Releases page and may trigger false positives from antivirus software. Users have reported issues such as excessive memory usage and compatibility problems with older Windows versions. In contrast, the modern Notepad in Windows 11 has grown to approximately 352KB, with a total disk footprint nearing 5MB, leading to user backlash over its complexity. Windows 11 LTSC retains the classic Notepad, while TinyRetroPad aims to demonstrate the potential of leveraging existing OS capabilities rather than adding unnecessary features.
