Export (ctrl+E) transfers all BOS events on file to another location, either on the same PC or another PC in the network. The safest method is to Browse for the target location, or copy/paste a path that you know works.
This function is intended for a once and for all export of the BOS events. You should first Export all and then set up the subscribe function if you want a continuous export of your deals.
You should use DupSoft's export function if you only want to export a particular deal file (instead of the entire BOS event).
