On Android devices, the hidden WhatsApp trash folder appears under Internal Storage/Android/media/com.whatsapp/WhatsApp/Media, where deleted photos, videos, audio and documents accumulate. Users who cannot see the hidden folder must enable the “show hidden system files” option in their file manager before navigating to the WhatsApp media path. iOS devices do not provide direct access to the hidden trash, with deleted files remaining in storage for up to 30 days before automatic removal. WhatsApp’s in-app “Manage Storage” tool helps users across both platforms to locate and delete large or frequently forwarded files in a single interface. Experts advise combining manual folder purges, regular device reboots and temporary message settings to prevent multimedia buildup and maintain optimal storage and performance.
