page build up

morning. I hope somebody can help with this .I have just been having a clear-out in my documents folder.
you know how you keep putting things in. Anyway I have been going from folder to folder deleting stuff.
and all of a sudden I noticed it getting slower and slower.so racked my brains trying to think what could be causing it. so I thought start from the beginning I red crossed it, and again and again and again.
I must have done it 20 times. so I went into task master and there was pages of them. why are these pages building up I have never noticed it before.

thanks layback bear I just right click and delete. You where right my recycle bin was full. I emptied it and all seems ok now.

Morning all. I spoke to soon ,it is still doing it .I delete stuff and it sends it to the recycle bin but it leaves it on the screen,(although hidden ) the pages just build up. when I am going back to desktop I red cross everything I have been working on and go back.now I find as many as 20/25 pages. I go into start manager and it is the same ,I have to click on them one at a time and click end task.
what have done wrong to get this.
