ERROR_CLOUD_FILE_PROPERTY_CORRUPT

The cloud-file property store cannot be interpreted reliably

ERROR_CLOUD_FILE_PROPERTY_CORRUPT identifies invalid property-store data associated with a placeholder. It differs from a checksum mismatch, which reports a specific integrity comparison, and from unsupported version, which can describe an otherwise valid format that the current reader does not support.

Determine whether the problem affects one property, every placeholder created by a provider build, or all objects on a volume. Compare property-store size and provider identity with healthy placeholders, and correlate the first failure with interrupted updates or schema changes. Reconstruct properties from authoritative provider metadata or recreate the placeholder after preserving local changes. Do not assume that hydrating file content repairs an independent property store.

What to inspect

  • Compare affected and healthy placeholders created by the same provider version.
  • Correlate corruption with interrupted metadata updates and filesystem events.
  • Rebuild property data from authoritative state instead of copying damaged bytes.
