Trillian stores your buddy list and all your settings in your profile directory. First step is to locate your profile directory. It is either in the users folder in your Trillian folder (usually C:\Program Files\Trillian\users\) or in C:\Documents and Settings\Your Windows User\Trillian\User Settings\. In Windows Vista, the files are stored in C:\Users\Your Windows User\AppData\Local\VirtualStore\Program Files\Trillian\.
