• Never store uploads inside the JAR or the project folder; they vanish on redeploy and the folder may be public.
• Use a configured directory outside the application (app.storage.dir), a mounted volume, or object storage such as S3 later (MID-056).
• Generate the stored name yourself, for example a UUID, and keep the original name only as metadata.
• Keep a record (ID, original name, content type, size, stored name) in your data model.
• Do not rely on the local disk if you run several instances.
