Thanks a lot for your reply.

What does it mean "protected storage"? Encrypted perhaps? In any case, these files must be stored in a concrete place in the filesystem, and this is what I need to know.

I have to say that all of this is a very peculiar design decision. I read elsewhere on this forum that journal application uses xournal file format, so it seems natural that the user would want to move the file to another machine on which xournal is installed.

But it seems that somebody put extra effort into making such portability as difficult as possible. I wonder why? Does enTourage seriously think that somebody will write important notes in journal, only to have them locked on a particular device? I use tablets for work which I want to be able to edit years from now - so it is out of question to have it stored in non-portable format.
