whats the most useful app?

[TheRatFink]

most useful for me is ..
Everything Search Engine, voidtools

i was just going to put that, pretty amazing piece of software it is. find anything instantly...

1.1 What is "Everything"?

"Everything" is an administrative tool to quickly locate folders and files by filename for Windows.
Unlike Windows search "Everything" initially displays every file and folder on your computer (hence the name "Everything").
You type in a search filter to limit what files and folders are displayed.

1.2 How long will it take to index my files?

"Everything" only uses file and folder names and generally takes a few seconds to build it's database.
A fresh install of Windows XP SP2 (about 20,000 files) will take about 1 second to index.
1,000,000 files will take about 1 minute.

Excluding firefox of course

Id say my most useful are CCleaner or Utorrent. Work good together. if i delete something I torrented but keep the torrent file I can then run a quick clean on ccleaner and get my space back.
