Claim 9:
10. A computer program product comprising instructions stored on a non-transitory computer-readable medium that, when executed by one or more processors, cause a mobile terminal to:
obtain a first operation from a user;
display, in response to the first operation, a first file on a first screen of a first application;
obtain a second operation from the user on the first screen;
change, 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;
encode, by using a preset coding scheme, metadata of the first file to obtain a target character string;
change a filename of the first file from a first name to a second name, wherein the second name is the target character string;
delete, 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;
obtain, after deleting the first data table, a third operation from the user;
