Determines, how SPLOT will handle situation, when you will select more items and at least one item is batch file.

The first (default) option is to allow to join the one batch file only with other non-batch items (files/folders). So if you will select more than one batch file, then no SPLOT menu item will appear in context menu.

The second option is full merge. Then SPLOT merges all selected items to one batch tasks. All selected non-batch items (files, folders) are added to the batch file/folder list and all batch files are joined to one task (but generally it is not recommended to select more than one batch file, because the result can be confusing).

The third option is to allow to join only batch files. So if you will select more items and at least one item is batch file, then also all other items must be batch files, otherwise no SPLOT menu item will appear in context menu.

The last option is to disable batch file merging. Then if you will select a batch file, then no other item can be selected, otherwise no SPLOT menu item will appear in context menu.
