File upload is the process of transferring a file from a local device, such as a computer or smartphone, to a remote server or cloud storage. This action allows users to share documents, images, or other types of files with others or store them online for easy access. Common platforms that support file uploads include email services, social media sites, and cloud storage providers like Google Drive and Dropbox. During a file upload, users typically select the file they wish to upload through a user interface, which may include a button labeled "Upload" or "Choose File." Once the file is selected, it is sent over the internet to the designated location. The speed of the upload can depend on factors such as file size and internet connection speed.
