File migration method, electronic device , and storage medium

An electronic device, wherein a main space, a private space, and a first application are disposed on the electronic device, a filesystem of the electronic device is a filesystem in user space, and the electronic device comprising:

• one or more processors and one or more memories, wherein the one or more memories store one or more programs, and when the one or more programs are executed by the one or more processors, the electronic device is enabled to perform the following steps:
• receiving a first access request of the first application for a first-type file in the main space, wherein a space running the first application is the private space, and the first-type file comprises any one of a picture, a video, audio, and a contact;
• when determining that the first application has a read permission on the first-type file in the main space,
• redirecting, in response to the first access request, a content provider corresponding to the first-type file from a second content provider in the private space to a first content provider in the main space, wherein the first content provider is used by the first application to obtain the first-type file, wherein the redirecting comprises:
• querying an identity document of a main space user from an Activity manager service;
• returning the identity document of the main space user;
• and
• obtaining the first content provider based on the identity document of the main space user;
• receiving a first migration request of the first application for a first specified file in the first-type file in the main space, wherein the first migration request is used to request to migrate the first specified file from the main space to the private space;
• and
• in response to the first migration request, migrating the first specified file from the main space to the private space when determining that the first application has a read and write permission on the first-type file in the main space, wherein the first application is a file migration service configured for migrating files between the main space and the private space.

A non-transitory computer-readable storage medium, wherein the storage medium stores instructions, and when the instructions are executed on a computer, the computer is enabled to perform the following steps:

• receiving a first access request of a first application for a first-type file in a main space, wherein a space running the first application is a private space, and the first-type file comprises any one of a picture, a video, audio, and a contact;
• when determining that the first application has a read permission on the first-type file in the main space,
• redirecting, in response to the first access request, a content provider corresponding to the first-type file from a second content provider in the private space to a first content provider in the main space, wherein the first content provider is used by the first application to obtain the first-type file, wherein the redirecting comprises:
• querying an identity document of a main space user from an Activity manager service;
• returning the identity document of the main space user;
• and
• obtaining the first content provider based on the identity document of the main space user;
• receiving a first migration request of the first application for a first specified file in the first-type file in the main space, wherein the first migration request is used to request to migrate the first specified file from the main space to the private space;
• and
• in response to the first migration request, migrating the first specified file from the main space to the private space when determining that the first application has a read and write permission on the first-type file in the main space, wherein the first application is a file migration service configured for migrating files between the main space and the private space.
