Version control (GiT?) for TDP Workbooks

What do you use for version control for Workbooks (.twf file) . With the other Toad files (.tas, ,tsm, .dcp etc.) they seem to be xml based so the source control can track changes. Is there a way to save .twf files in such a "text" format?

Short answer is that the TWF files (Toad Workbook files) are not XML-based, so yeah, version control won't help much there. However, it's an excellent suggestion, and a valid use case. I've submitted as an enhancement suggestion for our R&D org to consider. Alternatively, I would encourage you also to submit this idea in TDP's Idea Pond here.
