I like the list a lot
It looks almost like the list of my favorites, except just:
- FastStone Image Viewer - IMHO best image browser. Freeware (not for commercial use). XnView is also a good alternative.
- foobar2000 - music player. Previously I used Aimp, which looks more like lightweight version of Winamp.
- jEdit - my favorite plain text editor. Very powerful. Its only drawback: it's written in Java
- WinDirStat - shows statistics and draws treemap of disk usage.
