 **Unterstuetzte Formate:** Bilder (JPG, PNG), Dokumente (PDF, DOCX, TXT), beliebige Dateien.
 Bilder werden in der App inline angezeigt, andere Dateien als Icon + Dateiname.
 
+**Re-Download:** Wird der lokale Cache in der App geleert (Einstellungen → Anhang-Speicher → Cache leeren),
+werden fehlende Anhaenge automatisch ueber RVS vom Server neu geladen. Der Speicherort
+ist in den App-Einstellungen konfigurierbar.
+
+> **Tipp Speicherplatz:** Das Docker Volume `aria-shared` liegt standardmaessig auf ARIAs VM-Disk.
+> Bei vielen Uploads kann das den Speicher der VM belasten (dort laufen auch alle Container).
+> Empfehlung: Das Volume auf ein Netzwerk-Filesystem mounten (CephFS, NFS, GlusterFS):
+> ```yaml
+> # docker-compose.yml
+> volumes:
+>   aria-shared:
+>     driver: local
+>     driver_opts:
+>       type: nfs
+>       o: addr=nas.local,rw
+>       device: ":/exports/aria-uploads"
+> ```
+> So bleibt ARIAs VM-Disk sauber und die Uploads liegen auf dediziertem Storage.
