# File
## Create a file upload session
`$ lightfield file create`
**post** `/v1/files`
Creates a new file upload session and returns an upload URL.
After uploading the file bytes to `uploadUrl`, call `POST /v1/files/{id}/complete` to finalize the upload. Optionally pass `purpose` to validate MIME type and size constraints at creation time. See [File uploads](/using-the-api/file-uploads/) for the full upload flow, supported purposes, and size limits. If you are uploading a meeting transcript, see [Uploading meeting transcripts](/using-the-api/uploading-meeting-transcripts/) for the follow-up meeting attachment flow.
**[Required scope](/using-the-api/scopes/):** `files:create`
**[Rate limit category](/using-the-api/rate-limits/):** Write
### Parameters
- `--filename: string`
Original filename.
- `--mime-type: string`
MIME type of the file. Must be allowed for the given purpose (if specified).
- `--size-bytes: number`
Expected file size in bytes. Maximum 512 MB.
- `--purpose: optional "meeting_transcript" or "knowledge_user" or "knowledge_workspace"`
Optional validation hint. When provided, the server enforces purpose-specific MIME type and file size constraints. Use `meeting_transcript` for files that will be attached to a meeting as its transcript. Use `knowledge_user` or `knowledge_workspace` to add the file to the authenticated user's or workspace's Knowledge, making it available to the AI assistant. Not persisted or returned in responses.
