Resetting Data
All JwC data is held in a series of private databases, all but the Primary dedicated to specific tasks, such as storing Photographs.
Nearly all are meant to be specific to one, and only one, Congregation.
Reset's primary purpose is to remove all data regarding a specific Congregation in which you no longer serve as an elder.
The Resetting Data button on the opening page removes nearly all contained PRIMARY data.
It DOES NOT remove personal notes, maps, photos, user settings, Service Calls, and "other phones" you've added unless you specifically request that.
However notes (other than for Service Calls and Other Phones), maps (other than for Service Calls), and photos become inaccessible until the associated entities (person, place) are again created.
However, if, on bringing in new initial data you indicate you have changed congregations, such previous notes, maps, and photos are removed as well.
Should any database become corrupted you can use Reset to restore JwC to "like new", except for Settings.
Note: Deleting the user-visible JwContactsUD files does NOT remove ANY data.
These files are hidden within Windows and can only be removed by an "Uninstall JwContactsUD" pre-programmed action.
Another way of putting this: The entire set of Jwc files visible to the user can be completely replaced without affecting data.
Exception: If the new files contain a different database schema, first run should cause Jwc to do a database update.
