how to delete all sample data

Actually I was also trying to find out if there was a way to remove sample data.

of course possible.

First step > Deleted local db file. e.g. C:\Users\Mehmet\Documents\SambaPOS3\SambaData3.sdf

Second step > Uninstall SambaPOS3

Third step > ReInsall SambaPOS V3, but not selected SampleData check box.

I deleted my DB and then updated my tables and menus in the import folder files and reinstalled SambaPOS 3 with import sample data option checked,

Guess what, it rebuilt the databases with my own tables and menus, good stuff... saved a lot of time and effort of creating categoreis and menus manually.
