A file download is the process of transferring a file from the internet or a remote server to a local device, such as a computer or smartphone. This allows users to access documents, images, software, and other types of files directly on their devices. Common file formats include PDF, JPEG, and MP3. To download a file, users typically click a link or button on a website, which initiates the transfer. Once the download is complete, the file is saved in a designated folder, often the Downloads folder, where users can easily find and open it.
