Part of KillerTools.net.

Features

• Filename search with wildcard patterns (*.log, report_*.xlsx, etc.)
• Content search streams through files line by line without loading them into RAM
• Multicore engine: The scan parallelizes across every CPU core
• Multiple search terms in a single pass, each independently tracked
• Filters by extension, date modified, and size, plus include/exclude patterns and a case-sensitive toggle
• Tabbed searches: Each tab is a full independent search; drag to reorder, optionally restored on the next launch
• Search within results: Pipe one search's results into a new tab and drill deeper
• Sort results by name, location, size, or modified date; Ctrl+F filters the list live
  (Yo dawg, I heard you liked search...)
• Results show matched lines with line numbers; open files directly or reveal them in Explorer
• Export to a self-contained HTML report (with its own theme switcher) or CSV
• Six killer themes with live accent colors; UI localized in 8 languages
• Run portable or use the built-in per-user installer (/silent installs machine-wide for winget/RMM)

• Windows 10 or 11 (x64)
• .NET Framework 4.8 (included in Windows 10 1903+ and Windows 11)
