Most of the messaging apps are “secure” hence save their data, downloads in locked space. They do allow one to save a particular image or file anywhere but it is a manual process not practical if I want to access all images I received in the last 5 years.

WhatsApp has been good for me in this regard because it saves them in a user accessible directory. But recently WhatsApp has made it impossible to use offline as backup because it refuses to read from it in a new phone. Only Google Drive backup is allowed.

Is there any other app which allows storage in a user accessible location?
