Many software packages (particularly the larger ones) from Check Point come packaged as a .ISO image file. Since these images usually need to be burned to a CD/DVD before they can be used (or even read), they're a bit cumbersome to work with. Windows lacks a native file viewer for this format but luckily there's a very good freeware program available:

Virtual CloneDrive from SlySoft.com

Just install it and now you've got a native viewer for .ISO image files. Double click on the .ISO file and an Explorer window will open, bound to a new drive letter, that will let you explore the contents.

It's a small tool and it solves a small problem, but it's really useful as part of your Check Point Firewall Administrator's Toolkit.
