Everything (software)
Type part of a filename and the match appears as you type, across every local drive. That is the whole pitch, and nothing in Windows itself comes close.
Everything indexes names rather than contents, which is why it is so quick: a fresh Windows 11 install of around 250,000 files takes about five seconds and roughly 35 MB of memory. On NTFS it keeps itself current from the drive's change journal, so the index is right even after a reboot. Content search exists but is slow, because contents are not indexed; for finding that spreadsheet someone saved somewhere odd, though, it is the first thing to install.
