Hi, > The DataStore maintains only one copy of each file.
Exactly - this saves a lot of space. > file naming is based on the SHA-1 digest of the file contents Yes. In theory, you could write a persistence manager wrapper (a PersistenceManager that calls another PersistenceManager and does some other stuff), that maintains directories and soft links to the right file. This is just an idea. I'm not sure how you would do that in Windows (create a 'shortcut'?). Regards, Thomas
