Since InfoQube is a windows application, I would like to see the default location for the InfoQube databases (cant recall if they're called InfoBases or InfoQubes) stored under the My Documents folder in a subfolder call "My InfoQubes".
I routinely back up my user created content, and storing user content under My Documents simplifies backup since I only need to backup one directory and all of it's subdirectories and content.
I realize the files can be stored anywhere, but I instinctively went to My Documents to look for the datafiles at first....
Maybe the new file dialog could be modified to indicate if the InfoQube is single-user or multi-user. If single user, default location is as described above, and for multi-user, the user can browse to find the folder where they want it (typically a fileshare location outside the local machine)....
