Desktopfree

Lertaro is an open-source Windows utility that indexes local drives via the NTFS USN Journal and MFT for near-instant file search. It offers a popup search window, a docked inline search bar, fuzzy multi-keyword matching, file previews, and a plugin SDK for extending results and themes. It's built as a lighter alternative to tools like Everything and Listary for Windows users who search files frequently.
