Customizing Parts

You can rename the Parts.DBLib file to CompanyName.DBLib and the DBLIB will still be connected to the Parts_Backend.accdb.

You can also rename the Parts_Backend.accdb. After renaming the database you will need to open the DBLib file in Altium and connect to the renamed database file.
