Need help please

[KEVIN Lock]

a friend using an iMac with 10.2.8 has tried to trash 465 attachments 
from his attachments folder and accidentally dropped them onto the 
desktop.  The Desktop is full and the remainder are trying to sit on 
top of the HD icon.  It doesn't want to finish depositing them on the 
desktop and we can't do anything except access Eudora.

Any ideas for me here?
TIA
