Seeing Double

I know my data is good but when I copied it from my work area the collection manager does not recognize it as valid data. What could be wrong?

Sometimes while coping using a drag and drop method your mouse may have been a bit off the mark when you dropped your data.  Look for the occurence of another RCDATA01 directory under your top-level RCDATA01 directory.  It might look like  C:\mydata\RCDATA01\myinstid\RCDATA01\myinstid\myaggreg\00000516 

You might have just dropped the RCDATA01 into a lower directory. Since the collection manager looks up and down the tree for valid ResCarta data formats it can be confused by multiple top level names.
