I'm tried to hide whatsp nd telegrm files from gallery using esfile explorer app. But after a rebooting the files show in gallery again.

Also I tried to hide using mui file manager, but the folder is encrypted and when we use whatsp again then there is a new WhatsApp system folder generating.

If we hide the WhatsApp named folder using esfile explorer the WhatsApp files won't show on gallery in the other phones. Is that mui problem?
What should I do to hide? How you guys doing this? Is there any good ideas?
