If I share the same file (say, an image or a video) across multiple contacts in WhatsApp, does the app create multiple copies of the same file (increasing the storage use)? Or is it smart enough to link always to the same file, from each different chat?

  • we could test this with a huge file sent to one or two people. But since max size is capped at a small figure, you have to send it over to multiple people, multiple times to cause a significant change in storage

Only the developer of the iOS client app can answer this. Basically, the answer depends on how the WhatsApp iOS client manage the files locally.

The most reasonable approach would be to avoid duplication by using some kind of mechanism to identify a media file's identify and maintain a single on-disk copy.

While this could be attested to based on empirical evidence, only the actual developer of the app can give an affirmative answer to this.

  • Do you know some other Community where I could ask about this stuff?
