I`ll try to tell the story as short as possible but it wont be easy.
So when i got my pc like 6 months ago, i installed windows xp home, ofcourse i had to register it but i didnt, tried like 20 serials and 100+ cracks(ok maybe thats a bit much but i really tried a lot) after a while i got so tired of it i just gave up, so every 30 days i simply put the HD of my old pc in this one, copied it all there and reinstalled windows. Then i thought what if i choose the option "delete old windows installation files and install again" well something like that, it just meant that i wouldnt have to format and put all the files on my old pc. I did that a few times, everytime i did it a new folder was created under documents and settings with the new username. I know this is a really stupid way of working but only now i realise how lazy i was, so my main files were still in the old user folder but now after the last time when i try to acces that file it simply says "Toegang geweigerd"well thats in dutch dunno how its correctly translated, so the problem is (please dont kill me

Theres 5Gb of music
20+Gb movies
20+GB applications
and lots of personal documents
when i goto the C to properties it still says i used 95GB wich cant be just the things i have now but the folder is 0KB large and when i search for music i cant find it, it has to be somewhere but i cant acces it
Can anyone help me with this or is it to late to save my lazy ass? if you can youll be the Macgyver of computer sciences.
btw ive got win pro with working serial now so it wont happen again
