Protecting your contact list
If you lose ICQ due to a hard disk failure or other failure, it?s easy to reinstall it, but what about your contact list?
ICQ stores your contact list and a history of your communications in a database in a folder called NewDB (or just DB in older versions of ICQ). You can resurrect your contact list provided you first back it up. To do so, open Windows Explorer and locate the database folder (it?s usually in Program Files\ICQ\NewDB). Copy the entire folder to a new location.
To restore the list, first complete the ICQ installation and then copy the contents of the backup folder into Program Files\ICQ\NewDB, overwriting any existing files.
You can use the same technique to copy your contact list to another computer running ICQ.
