Call of Duty: Black Ops III stores its save files at C:\Program Files (x86)\Steam\steamapps\common\Call of Duty Black Ops III\players on Windows. Checkpoint64 already knows this folder — it backs it up automatically and keeps earlier versions, so a corrupted or overwritten save is one click from restored.

Sharing Call of Duty: Black Ops III saves with friends
Call of Duty: Black Ops III has co-op, so the folder above usually lives on one person's PC — whoever hosts. When they're offline nobody else can carry on, and if two people play separately, one session quietly overwrites the other.
Checkpoint64 lets a small group pass one Call of Duty: Black Ops III world around instead of renting a dedicated server. Whoever plays next takes a server-enforced lock, pulls the latest save, plays, and pushes it back; everyone else stays read-only until the lock frees up, so nobody saves over anybody. Recent versions are kept, so a bad session is one restore away. The dedicated server alternative guide walks through the full take-turns flow.
