Abstract: During the last decade, mobile usage has increased dramatically. Due to the potential of mobile devices, technology is now widely used by many people. The Internet with the mobile, gives the mobile many additional features like file sharing (images, videos, audios, documents) by social media network apps, exchanging information among relatives and friends. This also means that mobiles receive numerous similar files via applications. As a result, there are many drawbacks, such as save duplicate files in the device's storage and low performance in (CPU, RAM, and battery). In this paper, we suggest and design an improved scheme to eliminate duplicate files. The duplicate files are eliminated using a Message Digest 5 (MD5) hash function, the American Standard Code for Information Interchange (ASCII), and Fast Fibonacci. These methods are used to generate a unique code that can remove the duplicate files in a fast and efficient way. As a result, we got a good result in storage and performance of the mobile device.

Key-words: Duplicate files; Mobile Device; Hash Code, MD5, Fast Fibonacci.
