TESIGN TAKE

What sets it apart for Everything users is the MIT licence, the .NET plugin SDK and the native ARM64 build.

A summary, not legal advice.

WHY IT MATTERS

It folds what Everything and Listary each did — instant file search and a launcher — into one MIT-licensed open-source tool. Instead of walking directories it reads the NTFS USN Change Journal and $MFT directly, with a background service keeping the index in sync in real time. Native x64 and ARM64 (Windows on ARM) builds ship together, and an inline bar docks into Open/Save dialogs and file managers such as File Explorer and Total Commander.

BUILD FROM THIS

  • With the .NET 10 C# plugin SDK you can add an internal document store or wiki as a search provider and register frequent commands as aliases and actions; it is also compatible with Flow Launcher community plugins.

WHO IT'S FOR

Windows power users
a file search and launcher replacing Everything/Listary
Windows on ARM (Snapdragon) laptop users
the native ARM64 build
.NET developers
custom search providers and actions via the plugin SDK

START IN 5 MINUTES

# 1. x64: download and run https://github.com/Lertaro/Lertaro/releases/latest/download/Lertaro-Setup.exe (recommended, supports the background service)
# 2. ARM64: https://github.com/Lertaro/Lertaro/releases/latest/download/Lertaro-Setup-arm64.exe
# 3. No install: unzip Lertaro-Portable.zip (ARM64: Lertaro-Portable-arm64.zip) and run
# 4. Build from source on Windows 10/11 with the .NET 10 SDK: build_and_run.bat (x64 and ARM64 Release builds: make.bat)

CAVEATS

  • Licence MIT. Windows 10/11 only (x64 and ARM64). Low-level indexing covers NTFS/ReFS; FAT32/exFAT is handled by monitoring. The installer runs a SYSTEM-level background service. The project started in August 2026 and its README warns to download only from official sources. Whether a separate .NET runtime install is required: [확인 필요].
