In the single-user version, your Xpert-Timer database is stored locally as an Access database or SQLite database. You can find the database in your installation directory in the "Database" folder. The Xpert-Timer database is stored as xt.sqlite or xt.mdb.
Your connection data and personal settings are stored in the xperttimer.ini file. You can see where your .ini file is located under the "Help" menu item in the Project Manager. Select the sub-item "About Xpert-Timer" and then the "System Info" tab. There you will find further useful information.
If you work with an SQLite or Access database, Xpert-Timer automatically creates data backups. By default, the path points to: C:\Documents and Settings\Username\My Documents\Backup XpertTimer
There you will find the backups for your database. The file names include the date and time of the backup.
If you use an MS-SQL or MySQL/MariaDB database, you can simply reinstall Xpert-Timer on your new system and connect to the corresponding database. To establish the connection for the first time, start Xpert-Timer while holding down the CTRL key. This opens the connection dialog before startup, allowing you to select the appropriate database.
