When you work in a shared environment managed by File Manager, where other users in your account are working on the same files at the same time, it may happen that some changes are being introduced by others to the files or folders that you are processing or viewing at any given moment.
This is where the Refresh option might come to the rescue. This feature lets you reload the contents of a folder and see its most current state. Whenever you need to see the updated file list, click the Refresh button from the File Manager Toolbar.
