File and Directory Restoration is designed for normal files and directories under the cPanel account, but it does not replace every type of account restoration.
Current cPanel documentation specifically notes that this interface does not restore the account's .cpanel and mail directories. Those types of account data require a broader account restoration method.
If the missing data is an individual website file, the file-restoration interface may be ideal. If the problem affects complete account configuration, mail storage, or multiple account components, do not assume a single-directory restore is sufficient.
