DB Commander is a utility developed by T&T Solutions that is commonly used to edit DBF files. It is one of the primary tools used by roster patchers offering more stability and less risk of corrupting files than commercial software such as Microsoft Excel and Microsoft Access.
One of the main advantages of DB Commander is its ability to open two database files simultaneously. This allows patchmakers to refer to values in a second database while making changes in the first, which is particularly useful when changing a player's nickname or a team's plays through DBF editing. It is also useful for copying data between DBF files.
