Microsoft Windows: "We're preloading File Explorer so it launches faster." File Pilot: Compiles in less than 3 seconds. Launches instantly. Eats whole drive for breakfast. Speed isn't a background task, it's design.

Tested: Windows 11’s ‘faster’ File Explorer (preloaded) is still slower than Windows 10. On a 4GB RAM test machine, File Explorer used ~32.4MB of RAM without preloading. After turning on preloading, Windows quietly adds ~35MB more. So Explorer now sits at ~67.4MB in memory before you even open it. 35MB isn’t a big deal in 2025. Your browser eats that for breakfast. That's not the point of my testing. Why is the preloaded File Explorer still slower than Windows 10? I made a video to compare the two versions.

Recently had the chance to talk with Vjekoslav Krajačić his File Pilot! It's a file explorer alternative, made from-scratch with modern design and incredible performance! Vjekoslav Krajačić, thank you so much for joining me! It was great!

Microsoft’s preload trick works for launch speed.... but it just doesn’t fix the deeper performance problems users have been shouting about since Windows 11 shipped. Watch the before-preload and after-preload comparison of File Explorer on Windows 11. It's faster. Video in slow motion.

So not only are we building File Pilot as a solid File Explorer alternative, we might actually be nudging improvements to it as well! That's a win either way.

Just found out an active File Pilot community member Thomas Klemenc made a task manager inspired by it! Handmade from scratch, C++, win32, D3D custom renderer, 1.55 MB. More of this in my feed, less AI slopware.

Windows 11 extracts 7z file at breathtaking pace of what seems like about a file a second. I don't usually trust the progress bars but it's been doing this for an hour now so actually 5-6 more hours seems on point. Far Manager extracts the archive in 11 seconds. This is on SSD.

Vjekoslav built a Windows file explorer from scratch. 2.3MB executable. No VC runtime. He threw away the standard library and wrote his own.

Officially not skill issued in neovim anymore. I built the most memory-efficient file picker UI available in Neovim, and it's the first one to actually use async I/O for file previews. We allocate 3x less memory than the pure lua pickers while mainting custom binary and file index in memory.
