## Get file metadata
**get** `/v1/compliance/apps/chats/files/{claude_file_id}`
Retrieves metadata for a file referenced in chat messages, without
downloading the file content. Use the sibling `/content` endpoint to
download the bytes.
### Path Parameters
- `claude_file_id: string`
The file ID (tagged ID, e.g., claude_file_abc123)
### Header Parameters
- `"x-api-key": optional string`
### Returns
- `id: string`
File ID
- `claude_chat_ids: array of string`
Chats this file is attached to. A file can be referenced by messages across multiple chats.
- `created_at: string`
File creation timestamp
- `filename: string or null`
Display name of the file, if set
- `md5: string or null`
Lowercase hex MD5 of the file's preferred downloadable variant, as recorded at upload time. Null when no stored hash is available. The sibling `/content` endpoint also sets a `Content-MD5` header (base64 per RFC 1864) computed over the exact served bytes; when the two disagree, the header is authoritative.
- `message_ids: array of string`
Chat message IDs this file is attached to. A file can be referenced by multiple messages.
- `mime_type: string or null`
MIME type of the file's preferred downloadable variant (e.g. 'application/pdf'). May be null for files with no downloadable content (e.g. code-interpreter outputs).
- `size_bytes: number or null`
Size in bytes of the file's preferred downloadable variant, if known
