Duplicate photos, videos, and other files are data duplicates, similar to photos or videos in terms of content but differ in terms of the location where they are stored. Data duplication is making two or more copies of a particular file.

Duplicate photos, videos, and other files can be created for many reasons. Sometimes, it results from a data breach, where hackers steal data from a server and publish it on the Internet. Other times, it could be because of the mobile phone's memory, which is often the case with Android. Still, another reason could be the user's desire to have a copy of the photo or video.
