Intro: Hi, John. I'm a long time (ab)user of PortableApps and also a Drupal user but this is the first time I'm going to make an app request. Thanks for the opportunity :-).
What it is: A free file finding and text searching tool with latest release "Release 3.50a" dated 2006-11-02
"You may use the Software without charge.
You may distribute exact copies of the Software to anyone. "
"Flexible configuration options and storage
-Many configurable user preferences
-Preferences can be saved to a file, the registry or not at all on exit
-Preferences are loaded from a file in the local directory, a file in the application directory or the registry (in that order)
-Preferences can be loaded and saved at any time by the user, and shared with other users
Single small executable, no installer
-No installation needed, start using the tool immediately
-Small executable can be run from the network
-Easy to temporarily install and then completely remove"
My personal remarks: I've been using this software for quite some time now (years) and I find it quite indispensable as it works extremely fast, has a very small footprint and is very convenient to use. I also find their other product BareTail very useful for my own purposes.
For your consideration. Thanks!
