It will only appear if you have deleted something from that drive via the Recycle bin when like I say it will get rebuilt.
What you can delete without fear is any instances that are not related to the ID for your profile on your machine, you won't be able to delete the one for you current ID because it will be locked.
So if you have more than one entry and your are the only person ever on that machine (i.e you don't have other acounts on it), and you don't use a multi/dual boot setup then deleting anything that is deletable in the $Recycle.bin folders on each drive will be safe to do as sometimes IDs will linger from an older OS that may have as one time been accessing the drives for example.
But hey Mike what do I know?
Ignoring people makes you seem mean spirited especially when they are trying to help.
