ERROR_REPARSE_TAG_MISMATCH
The supplied tag does not identify the existing reparse point
Windows requires the tag supplied to a get-modify-delete workflow to match the tag currently stored on the object. This prevents an application that expects one reparse format from interpreting or deleting another. The error commonly appears when a path changed between inspection and modification or when code hard-codes a tag instead of reading the object first.
Open the reparse object itself, call FSCTL_GET_REPARSE_POINT, and use the returned tag for any authorized modification or deletion. Recheck after races involving rename, placeholder conversion, symbolic-link replacement, or provider view changes. A tag mismatch is not fixed by changing only the payload; the caller must understand and own the actual format now attached to the file or directory.
What to inspect
- Read the current tag through the same object handle.
- Check for replacement races between inspection and update.
- Do not delete a point whose tag belongs to another provider.
