We have seen some misunderstandings on how you can name and save files you create in Keywin Light compared to the file you export.
The explanation is that when you create a file in Keywin Light you get an opportunity to name the database you create but when you are to export the information you have created in the database you do not get the opportunity to choose a file name, the file is automatically created and saved in the name cabinet.cfg, and it has to be that name and format for the cabinet to be able to read it.
