ResourceWorldResetter v4.1.1 fixes world-folder detection on Paper 26.1 so disk checks and deletes target the real resource world data folder instead of a missing server path. It also avoids the Windows 0 GB false positive by resolving usable space from the actual world folder when it exists, or the server root before the folder is created.

What changed

• Shared world-folder resolution for loaded worlds, classic standalone layouts, Paper 26.1-dimension storage, and primary-world save roots.
• Preflight disk checks now use the resolved world folder instead of a missing server/world path.
• Reset deletion and history snapshots now resolve the same safe folder.
• Delete safety now blocks Paper multi-dimension save roots while still allowing classic standalone worlds and dimension folders.
• New tests cover Paper 26.1 resource discovery, overworld mapping, legacy layout, and delete safety.

Upgrade notes

2. Replace the plugin JAR with v4.1.1.
3. If you run Paper 26.1, run /rwr reset dry-run before the next scheduled reset.
4. Verify /rwr status and /rwr next after restart.
