Why neoSearch? Because it the most
simplest lightweight search tool
available today. What I like the most
is the fast indexing speed and the
real-time search results, which
according to the developer, are
displayed in less than 0.01 seconds
after you type a keyword or hit Enter.
LAN Search Pro – Free network file locator
LAN Search Pro is a powerful utility
for fast file searching across your
LAN. You can search for specific file
names or for specific file types (e.g.
all MP3 files). LAN Search Pro
provides a lightning fast search
engine and includes the ability to
search hidden network resources,
restricted access resources, IP
subnets, LAN FTP servers and much
more. It comes with a built-in
password manager to store your network
logins for resources with restricted
access. Besides the file searching
capabilities, LAN Search Pro offers
features that allow you to perform
actions on the found items – copy,
move, rename etc. Additional features
include result sorting, filtering,
export, search within results,
