1. A method implemented by a mobile terminal, wherein the method comprises:
obtaining a first operation from a user;
displaying, in response to the first operation, a first file on a first screen of a first application;
obtaining a second operation from the user on the first screen;
changing, in response to the second operation, a storage location of the first file from a first directory to a second directory to display the first file on a recycle bin screen of the first application, wherein the second directory is configured to store one or more files displayed on the recycle bin screen;
encoding, by using a preset coding scheme, metadata of the first file to obtain a target character string;
changing a filename of the first file from a first name to a second name, wherein the second name is the target character string;
deleting, after displaying the first file on the recycle bin screen, a first data table to remove the first file from view of the user on the recycle bin screen;
obtaining, after deleting the first data table, a third operation from the user;
obtaining, in response to the third operation, the metadata by decoding the second name by using the preset coding scheme; and
generating, based on the metadata, a second data table to make the first file visible to the user on the recycle bin screen.
