It will take days to permanently delete files

I am trying the shift click and scroll to last file to delete, but if i select more than 100 items I start getting error messages and the page locks up. I have used 30 minutes to delte .1GB of my 72GB.

I really can´t spend the time to do this. Is there really no other way than to switch to a different cloud storage solution? By looking at older posts I looks like Adobe has had this problem for a while and not fixed it.
