   File rewinding restores files on disk to a previous state. It does not rewind the conversation itself. The conversation history and context remain intact after calling `rewindFiles()` (TypeScript) or `rewind_files()` (Python).
 </Note>
 
-The checkpoint system tracks:
-
-* Files created during the session
-* Files modified during the session
-* The original content of modified files
-
 When you rewind to a checkpoint, Claude Code deletes the files it created and restores the files it modified to their content at that point. Claude Code skips a tracked path that is a symlink, hard link, or other non-regular file. It also skips a tracked file whose parent directory no longer resolves to its checkpoint-time location, or whose backup it can't read safely. [`RewindFilesResult`](/docs/en/agent-sdk/typescript#rewindfilesresult) counts every skipped path in its `skippedLinks` field. Skipping requires Claude Code v2.1.216 or later; before v2.1.216, a rewind wrote and deleted through links at tracked paths.
