How does one transfer a .bam file?

Just recently opened BG2EE in EEKEEPER to observe it's contents. Though in terms of undiscovered or unreleased content the file were disappointing save the Wand of Maze, Wand of Shadowsteping, and a faulty Demon purging spear with a 50% to Banish a hit Demon, the .Bam files are phenomenal for constructing new items.

How can a .bam file be transferred from BG2EE to say BGEE or Icewind Dale with limited (to put it lightly) knowledge of Weidu?
