Thanks for your quick response.
Hey, I am in no way suggesting that Ccleaner is in anyway lacking, perhaps I could have worded it a little better. In fact I'd say that it's probably amongst the best free software available, and has far more features than IEX (secure deletion/registry/uninstall etc). However, having downloaded and tried IEX, I found the mentioned features extremely helpful. I'm not up on programming etc so don't know how difficult it would be to implement the features.
Sure, if I do decide to go IEX I will certainly still use CC for the other features.
Thanks again.
PS thanks for the link, I'll give it a try.
