Your Precious Data
Your address book consists of the following components located in the working
directory:
Core data -- A database file with extension name "GDB" contain essential
part of your address book, including contact names, sections, fields,
relationships and categories as well as almost all settings. The GDB files
is by default located in the Data directory under the working directory
unless the Main.INI points to elsewhere.
External files -- While the data fields can store names of external
resources like web page addresses and file names, the files pointed by the
file names are general stored in local computers or local area network. By
default, file names without file path point to files stored in the Files
directory of the working directory.
Template files -- While the whole design of Open Contact is very flexible
for all users, some users with advanced knowledge of XML/XSL/HTML can modify
some template files used by Open Contacts. Please read
XML
Explained for more details.
The database file is guarded by a long standing database engine called
Firebird. While Open Contacts and
Firebird provide reliable and speedy services to your precious data, it is
reasonable to backup the data regularly.
Sizes of your address books
To test the capacity and the reliability of Open Contacts, we have a few test databases. The
largest one contains around 31,000 contacts, each of which contains 20-40 fields
and memos, and each of fields contains 5-20 words.

It is not likely that every contacts of your address book contain 20-30 fields
and memos. The test databases are mostly for stress tests. The size of your
address book is generally much smaller. We have another test address book with
emulated contact info of 11,193 records, each of which has around 11 dynamic
fields. The size of the database is 22,792KB (2KB per record), and the size of
the backup file is 11,188KB.
