I think I recall seeing FileSeek back when 7 was new. Most of these you will find were intended for XP, Vista, and 7 when they first came out. A mountain of freebies suddenly appeared when 7 grew very popular from beta on! You saw a mountain of OS tweakers for XP even and especially for Vista to be followed by how to customize 7 back then.
Locate 32 is another one found in several places along with Everything. The other two one being MasterSeeker resembles both Everything and UltraSearch in a number of ways there while the Listary app is geared for previously Windows Explorer now File Explorer being the same thing the explorer.exe file in the Windows directory.
