  • fileSizeInBytes: number

    Size of the file in bytes. Used for progress tracking, quota validation, and file listings.

  • updatedAt: Date

    File's last modification date (creation or update). Tracks when the file was created (if new) or last updated (if modified). Used for cache validation, sorting, and auditing.
