You can double-click any .dlm file to have it imported into BOS. Note that both BOS and DupSoft must be closed when you do this type of import.
You should also make sure that the source file has a name to your liking BEFORE you double-click on it. This is so because the name of the source file will be the name of your BOS event and the event name cannot be changed after Import.
You can use DupSoft's import function if you have already created a BOS event when you realize that you have a deal file to import.
You need to Trash the event and start from scratch if you have made the mistake to randomize (new) deals when you wanted to import them from a file.
You have to create a new event, resume the last opened, or open an older event before you can select a program to run function in the main interface.
The BOS program must be running so long as you want to use its functions. Minimize the BOS Window if you do not want to see it on the screen.
You can use the Resume button if you have closed BOS and need to continue with an ongoing game.
