Comment Comment by userbinator I thought so too, given that MS has already released the source of the original File Manager:https://github.com/microsoft/winfile...and it compiles to a nice small and fast ~300KB executable, in contrast to their open-sourced and significantly less efficient UWP calculator:https://github.com/microsoft/calculatorI believe the old leaked Win2k source has much of the explorer.exe source, if you're really curious. parent userbinator 7 years ago
