oh the wounders of technology!!

Hi All
The title should say it all, but of course it doesn't, i hope what happened to me doesn't happen to any of you.
This week while working on my new website I managed to delete everything from my computer by accident!
That is everything from my photos to my new web pages which I'd spent months working on. I know your all asking how do you manage that - well it's like this you see - i run vista on my laptop which has this stupid hover mode on it, so the cursor when moved over anything will automatically take you to or do what it hovers over. So this means as I type this I don't need to use the cursor so it's left somewhere at the edge of the work, but in my case my cursor will jump to where it's left and continue typing where it jumped to.
With most things I'm usually very careful because i know this can happen but what happened on this particular occasion took me by surprise. I was trying to delete a file and left my mouse right at the top of the page sort of on the address bar. I was using the nav keys to go through the files and delete the ones I don't want, while doing this I get a dialogue box come up asking me if i want to delete this file, which of course I do because that's what i working on - only i didn't realise that the next box says are you sure you want to delete files? I hit the enter button to confirm but still hadn't read the whole sentence which must have said permanent delete on it.
Well i could have died when I realised what was happening - the cursor which was now hovering over the very top bar which read C:/computer/pictures and was hurriedly deleting all my files PERMANENTLY!!
Shock horror nothing i can do, but try to find a piece of software that will retrieve them.
I find one but it wont restore them in one piece their fragmented so I still cant use them.
Losing 4 months of website building was bad enough but when i realise that some of my photos of paintings I'd done had gone I was mortified. Many of these don't belong to me anymore and we have no idea who purchased them.
Don't you just love computers!!!
Guess what I'll be doing all summer ha ha
Moral of story make sure you back up everything somewhere else!!
Back to the drawing board.
