Fiery Crystal

I have various duplicated folders in my inventory. For instance I have 5,797 trash folders in my trash can. My 'main' trash can doesn't allow the option 'empty trash'. I can't delete the 5,797 trash cans in there. I've seen a similar problem in Q & A's but the link doesn't work & the suggestion on how to delete them doesn't work. I've uninstalled and reinstalled second life - same problem. Any suggestions?
