# Put a file at a specific path (object-storage style)

PUT /v1/files/{file_id}
Content-Type: application/json

S3/blob-style put-object: store the raw request body at the given key. The key is relative to the session's uploads mount (`/mnt/user-data/uploads/` inside the sandbox) and may be nested, e.g. `data/2024/report.pdf`; an explicit `uploads/` prefix is accepted and normalized away. Parent directories are created automatically and existing keys are overwritten. The response is the same `FileMetadata` as `POST /v1/files`, so the returned `id` can be used with the other file endpoints.
