File format
 

I like the program very much - even if it's still very buggy (contexts with search strings crash my iPhone, database slows down if you do not remove the .client-files on the iDisk...)

I do not have a Mac (yet) an so I have to stay with windows for the next time. I already wrote a little programm which reads the data from the iDisk and parses it. For creating own new data I would need to know how the id's and the filenames work. They seem to be base64-encoded. But what are they?
Are they just random numbers? Timestamps? Hashes over the data?
Can somebody help me please? A little windows application for just filling the inbox would help very much.
