Local filesystem refferences

Hi

I wonder if Wuala keeps track of the locations of files in the physical filesystem for the maintenance purposes. I mean, does it maintain only what's stored in its local cache or does it also "remember" physical locations of the files in case they were inserted from local filesystem? To put it simple: will the file c:\somewhere\something.jpg get reencrypted and maintained as needed even if it was deleted from the cache just not to duplicate the data on the same local hard drive? I think I saw some local path refferences while peeking at some Wuala database files but I don't know if this data is really being used.
