what is saved in c:\Documents and Settings\username\Jaikoz\jaikozdb\seg0\ ? This folder has more than 700megs.
Is it safe to delete it ?
Jaikoz folder
The internal database used by Jaikoz to store details of the tracks you’ve loaded, and info looked up from Musicbrainz.
You can empty it by using Advanced/Empty Cache but it wont release all the space. You can delete it when Jaikoz is not running without breaking anything but it will recreate it and start populating it when you start Jaikoz.
To get better performance and eventually alolow Jaikoz not to be memory bound the database is needed, but one option I will add is to chnage the location of where it is stored.
