Filesystem disks are configured in config/filesystems.php, each with a driver (local, s3, etc.) and root path. Files can be stored with public or private visibility, controlling whether they're accessible via a direct URL. Temporary signed URLs (Storage::temporaryUrl()) let you grant time-limited access to private S3 files without exposing credentials.
