EF Commander 7. 30.
Just received an email from the people behind the file browser of my choice. When I started using PC's there was no Windows, and DOS was still used commonly. Back then, I relied upon a double windowed file browser called Norton Commander and still today I refuse to use the (to me) infamous Windows Explorer. EF Commander inkludes several integrated tools such as Achiever (Zip, rar, etc) and FTP client, just to mention a few. It has become one of several tools I decided to migrate between windows upgrades (Windows 7). Other applications I strongly recommend are, Jet Audio, Fast Stone, Skype, AVG Inyernet security and essential Net tools...
Pros: Not to have to rely on MS poor File Explorer..
Cons: None
