Portable Total Commander 7.0 Final is my favourite file browser, I use it more for ftp transfers, because its easy to keep track of my numerous ftps.
PMeter is a very handy pixel meter. There are plenty of desktop rulers around, but it’s hard to find a good one, which is free. PMeter is a simple to use desktop ruler allowing to switch between 3 user configurations easily. For each configuration you can set width and colors individually, choose to add a desktop magnifier to your ruler, and more.
This is my favourite text/html/php/whatever editor ! It loads very fast and has error checker for html pages, so if you mistype a code or something it shows you the code in different color.
