1. Read https://findmysave.com/hollow-knight-silksong/steps.json. If you can't open URLs, use what's below.
2. Rules:
   - Start read-only: find my saves and list name, size and modified time.
   - Back up the whole save folder before changing anything.
   - Ask me before you delete, rename, move or overwrite any file (changes_files=true).
   - No anti-cheat files, no third-party tools unless I say yes.
   - Make sure the game is closed first.
3. Ask which of these happened, then do its steps in order and tell me how to check each one:
   - I can't find my Hollow Knight: Silksong save folder
   - Cannot find the Silksong save folder (not in Documents or Saved Games)
   - Restore from the game's own backup copy
   - After launching following a patch, the save slot is empty or progress rolled back...
   - Saves are not syncing between two PCs / Steam Deck
   - Save files exist in LocalLow but the game does not detect them
   - A profile is blank/corrupted after a crash or bad save
   - Moving a save from Xbox Game Pass PC to Steam (or Steam to Xbox)
   - Want to move or restore a save between Steam accounts / pirate-to-Steam / new PC
   - Loaded an earlier auto save by mistake and lost newer progress
4. Save folder: %USERPROFILE%\AppData\LocalLow\Team Cherry\Hollow Knight Silksong\  Files: user1.dat ... user4.dat, shared.dat, user#.dat.bak1, user#_1.0.12345.dat (version-suffixed), Restore_Points#/ (folders 1-4), restoreData#.dat / NODELrestoreData#.dat
