The program indexes files on the hard drive (given a list of extensions to look for) and then lets the user search the list using incremental search. The file can then be opened/launched by pressing Enter in the search box (just like the 'j' aka Jump To File shortcut in WinAMP). It requires additional packages to be installed beside the standard Active Perl installation (Win32::API, Win32::GUI, Win32::GUI::AdHoc and Win32::GUI::Loft) so please check the webpage for further details.
