The File Manager is cPanel’s built-in web application for managing and manipulating your website’s files from your personal computer. Most users will feel comfortable using this file management tool. cPanel provides a number of ways files can be manipulated within the File Manager.
Certain functions of the File Manager are designed for use with 1 file at a time. Any attempt to rename, edit, or view multiple files at once will open only one file — the file listed first in the directory.
