In one large cross-team project, we solved this by creating a “master map” — a document that listed every folder, what it was for, and who managed it. We combined that with a consistent naming system and access control so people only saw what was relevant to them. I also discovered on
https://ejoi2018.org/ that tracking who accessed what helps identify which folders are used most, so you can keep them prioritized. The result was a shared drive that felt organized, easy to search, and far less overwhelming for everyone involved.
