Sharing Minecraft (Prism Launcher) saves with friends
Minecraft (Prism Launcher) 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 Minecraft (Prism Launcher) 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. Every version is kept, so a bad session is one restore away. The dedicated server alternative guide walks through the full take-turns flow.
