“Unable to delete folders from CD recorder storage area”

I have a HP Pavillon A700n pc with win XP
512MB pc 2700
3000+ AMD Athlon processor

My system crashed aand I tried to burn my pics
while in safe mode (forgot to check the disks)
now I have 1.7 gigs in the CD temporary storage
area and it won’t delete info through ‘del temp files’ process so I can get to the cd disk
size to burn.
When I try, some folders are moved to the recycle bin but with 0 bytes.
Is there another process to use to accomplish
this. All help would be greatly appreciated
