Why Android says that I am using a lot of storage in pictures and videos? If I see the Internal Storage, it says that I am using 4.7 GB in "Pictures, videos". However, when I do click in it, I see the gallery, where in total I am using 93.98 MB!!

How is this possible? What is wrong? How to fix it and get more free space?

My phone is a HUAWEI P6-U06 with Android 4.2.2
Maybe the pictures and videos are hidden from the gallery.

Install "Total Commander" or another app to search on entire disk for files *.jpg, *.avi, *.mp4, etc.

Ensure you delete WhatsApp photos and videos.
