Which protocol allows users to edit and access files stored on remote devices?

File Transfer Protocol (FTP) is specifically designed for transferring files between a client and a server over a network. It allows users not only to upload files to a remote server but also to download files from it, making it a versatile choice for working with files stored on remote devices. FTP supports commands for browsing directories, deleting files, and performing other file management tasks, which gives users the ability to edit and manage files remotely.

In contrast, Secure File Transfer Protocol (SFTP) is a more secure version of FTP but may also serve to accomplish similar tasks with enhanced security measures. IMAP, on the other hand, is used for accessing and managing email messages stored on a server rather than file systems. Similarly, HTTP is a protocol used primarily for transferring hypertext and enabling browsing of web pages, not for direct file manipulation or editing on remote devices.
