DATA DOWNLOAD DUPLICATION ALERT SYSTEM

Abstract: The Data Download Duplication Alert System is a software system developed to help users avoid downloading the same file multiple times. Today, people frequently download documents, images, videos, software, and other files from websites, cloud platforms, and online repositories. Sometimes, the same file is downloaded again without the user realizing it. This can take up extra storage space, use more internet bandwidth, and waste time.The main purpose of this research is to develop a system that can check whether a file has already been downloaded and notify the user before downloading it again. The system keeps track of previously downloaded files and checks information such as the file name, size, type, and hash value. If the requested file is found to be a duplicate, the system displays an alert to the user. The user can then choose whether to continue with the download or cancel it.The system can be developed using Python, databases, and file hashing techniques. By detecting duplicate files, the system can help reduce unnecessary downloads, save storage space, and decrease network bandwidth usage. It can also make file management easier for users.The proposed system can be useful for individual users, educational institutions, and organizations. In the future, it can be improved by adding cloud storage integration, smarter duplicate detection, real-time monitoring, and automatic file management features.
