Deleting Files

[SIRCOOKS]

i have two problems:

1.[color=red] my trash bin in xp home stays with a full symbol on it even though theres nothing in it, then when i press empty recycle bin it always says if i wanna deleye these 4 items, then when i press ok, it says cannot remove folder Dc9: the directory is not empty.

2.[color=red] When ever i try to delete folders sometimes, i wont allow me too, it always tells me that the directory is not empty and i have a few folders on my hd that i wanna get rid of,

Anyone got any solutions besides formatting............
