Don,

Are you saying that it doesn't blow up if you process this folder first but always blows up on the third folder?

In this instance, I delete all the folder with the same code, by passing the Delete param. Use MD to create the new folders, programatically create tables, CDX's and views in each folder, copy in data, and then (where we are bombing) copy the folders to another location, which in production will be up to a file server.
