# Document retention and expiry

> Check when uploaded files expire, recover missing files or expired Parse results, and understand what deleting a file or Parse job removes.

Uploaded files use temporary storage. The Upload API specifies 24 hours and returns `expires_at`; use that timestamp for your file.

## Recover an expired file

Use the original document from your own storage, upload it again, and use the new `file_id`. A missing or expired uploaded file returns HTTP 404 on file retrieval. A file ID does not provide durable storage.

## Recover an expired Parse

Extract returns HTTP 409 with `parse_expired` when a Parse's output is no longer retained. Parse the original document again, then use its new `id` for extraction.

Retrieving a completed job can return HTTP 410 with `result_expired` when the job metadata remains but its stored result is no longer available. Re-run the original request to produce a new result.

Transform does not publish a fixed retention period for parsed results. Job metadata includes `result_state` and `result_expires_at`; use `result_expires_at` when it is present. A null value means the expiry is unknown, not that the result is retained indefinitely.

## Delete resources

Deleting an uploaded file removes it from temporary storage. Deleting a Parse job that has completed, failed, or been cancelled runs asynchronously. The job stops appearing in the API. The source and output data are not deleted at the same time. Do not assume either operation cascades to every related resource.
