The Java ME Platform SDK emulator stores contact, calendar, and to-do information in standard files on your desktop computer’s hard disk. All information is stored in:USER_HOME/javame-sdk/3.0/work/emulator-instance/appdb/filesystem/skin/pim.
This directory is shared by all running emulators. Lists are stored in subdirectories of the contacts, events, and todo directories. For example, a contact list called Contacts is contained in USER_HOME/javame-sdk/3.0/work/emulator-instance/appdb/filesystem/skin/Contacts:
Inside the list directory, items are stored in vCard (.vcs) or vCalendar (.vcf) format (see http://www.imc.org/pdi/). Contacts are stored in vCard format, while calendar and to-do items are both stored in vCalendar format.
