back-end programming

Full Stack Developers handle file uploading and storage in applications by using a combination of front-end and back-end technologies. On the front-end, they utilize HTML forms and JavaScript to create the file upload interface. On the back-end, they use a server-side programming language like Node.js or Python to handle the file upload process and server storage. They often use frameworks like Express or Django to simplify the implementation. The uploaded files are usually stored in a dedicated storage service like Amazon S3 or a server file system. The developers also need to consider security measures and file management, such as validating file types, setting file size limits, and implementing access controls.
