Abstract
The present disclosure relates to file access methods. In one example method, a first electronic device receives a trigger operation performed by a user on a sandbox file in a shared interface sent by a second electronic device, and sends an access request to the second electronic device. The second electronic device receives the access request, and determines mapping information corresponding to the sandbox file based on the access request, where the mapping information includes a mapping file corresponding to the sandbox file, a path of the mapping file, and a correspondence between the path of the mapping file and file index information of the sandbox file. The second electronic device sends the mapping information to the first electronic device. The first electronic device receives the mapping information, and may directly access the sandbox file based on the mapping information.
