Wherein the virtual file system is a database mapped by traversing a disk of a mobile terminal, a first file ID of the newly-added file is an ID of the newly-added file in the virtual file system, the first directory ID is a directory ID of an interface where the newly-added file is created by the external device, a first subdirectory ID of the first directory is an ID of a subdirectory under the first directory in the virtual file system, the first file ID of the first directory is an ID of a file under the first directory in the virtual file system, the second subdirectory ID is an ID of a subdirectory under the first directory when the subdirectory under the first directory is displayed in the disk of the mobile terminal, the second file ID is an ID of a file under the first directory when the file is displayed in the disk of the mobile terminal, and the second subdirectory ID belongs to information of the subdirectory, the second file ID belongs to information of the file.
Optionally, the first file ID of the newly created file in the virtual file system of the mobile terminal 11 corresponds to at least one first directory ID.
Optionally, before obtaining the first file ID of the newly added file, the mobile terminal 11 controls the mobile terminal to update the virtual file system when detecting that the newly added file is stored in the magnetic disk of the mobile terminal.
Optionally, the mobile terminal 11 uses a difference between the first sub-directory ID of the first directory and a first preset offset as the second sub-directory ID, and uses a difference between the first file ID of the first directory and a second preset offset as the second file ID.
Referring to fig. 2, which is a schematic diagram of an implementation flow of a file processing method provided in the second embodiment of the present invention, where the file processing method is applied to a mobile terminal, as shown in the figure, the file processing method may include the following steps:
step S201, when detecting that a new file is added to a virtual file system of the mobile terminal, acquiring a first file ID of the new file.
The virtual file system is a database mapped by traversing a disk of the mobile terminal, and the first file ID of the newly-added file is the ID of the newly-added file in the virtual file system.
Optionally, the mobile terminal and the external device are in a media transfer protocol MTP connection mode.
In the embodiment of the invention, when the MTP connection is established between the mobile terminal and the external equipment, the external equipment can check the files in the mobile terminal. The external device does not directly access the file in the disk of the mobile terminal, but accesses the file in the virtual file system mapped by the disk of the mobile terminal, that is, when the external device operates the file in the mobile terminal displayed by the external device, the external device operates the file in the virtual file system of the mobile terminal. In order to better distinguish whether the ID and directory ID of a file are the ID in the disk of the mobile terminal or the ID in the virtual file system, for the same file, the file ID of the file in the disk of the mobile terminal (i.e., the second file ID) and the file ID of the file in the virtual file system (i.e., the first file ID) may be set to be different, and the directory ID of the file in the disk of the mobile terminal (i.e., the second directory ID) and the directory ID of the file in the virtual file system (i.e., the first directory ID) may be set to be different.
Optionally, the first file ID of the newly created file in the virtual file system corresponds to at least one first directory ID.
Since one file in the magnetic disk of the mobile terminal is usually stored in one directory, in order to display one file in a different directory when the external device displays the file in the mobile terminal, the embodiment of the present invention may map the file ID (i.e., the first file ID) of the newly created file in the virtual file system to a plurality of directory IDs (i.e., the first directory ID) when the file in the magnetic disk of the mobile terminal is mapped into the virtual file system.
Step S202, an event of successfully acquiring the first file ID of the new file is sent to an external device connected with the mobile terminal.
In the embodiment of the present invention, the mobile terminal sends an event that the first file ID of the new file is successfully acquired to the external device, so as to trigger the external device to acquire the first directory ID of the currently displayed interface of the external device according to the currently displayed interface of the external device, and send the first directory ID to the mobile terminal. In the embodiment of the present invention, when the external device creates a new file, the mobile terminal is updated (that is, the new file is added to the mobile terminal), and then the external device is refreshed in real time.
Step S203, receiving the first directory ID fed back by the external device, and acquiring a first subdirectory ID and a first file ID of the first directory from the virtual file system according to the first directory ID.
The first directory ID is a directory ID of an interface where the new file is created by the external device, that is, the first directory ID is an ID of a directory to which the new file belongs in a file of the mobile terminal displayed by the external device or an ID of a directory to which the new file belongs in the virtual file system. The first subdirectory ID of the first directory is an ID of a subdirectory under the first directory in the virtual file system, and the first file ID of the first directory is an ID of a file under the first directory in the virtual file system.
When the external device accesses a file in the mobile terminal, the external device actually accesses the file in the virtual file system of the mobile terminal, that is, the file in the mobile terminal displayed by the external device corresponds to the file in the virtual file system, and according to the first directory ID fed back by the external device, all the subdirectory IDs and file IDs under the first directory, that is, all the subdirectory IDs and file IDs of the directory to which the newly-created file belongs in the virtual system, can be acquired from the virtual file system.
Step S204, a second subdirectory ID corresponding to the first subdirectory ID of the first directory is obtained according to the first subdirectory ID of the first directory, and a second file ID corresponding to the first file ID of the first directory is obtained according to the first file ID of the first directory.
The second sub-directory ID is an ID of a sub-directory under the first directory when the sub-directory is displayed in a disk of the mobile terminal, and the second file ID is an ID of a file under the first directory when the file is displayed in a disk of the mobile terminal.
Optionally, the obtaining a second sub-directory ID corresponding to the first sub-directory ID of the first directory according to the first sub-directory ID of the first directory includes:
taking the difference value between the first subdirectory ID of the first directory and a first preset offset as the second subdirectory ID;
acquiring a second file ID corresponding to the first file ID of the first directory according to the first file ID of the first directory comprises:
and taking the difference value between the first file ID of the first directory and a second preset offset as the second file ID.
In order to distinguish all subdirectories and files of the directory to which the newly created file belongs in the virtual file system from all subdirectories and files of the directory to which the newly created file belongs in the disk of the mobile terminal, a difference value between a subdirectory ID of the directory to which the newly created file belongs in the virtual file system and a first preset offset value can be used as a subdirectory ID of the directory to which the newly created file belongs in the disk of the mobile terminal, and a difference value between a file ID of the directory to which the newly created file belongs in the virtual file system and a second preset offset value can be used as a file ID of the directory to which the newly created file belongs in the disk of the mobile terminal.
Step S205, obtaining the information of the subdirectory according to the second subdirectory ID, and obtaining the information of the file according to the second file ID.
Wherein the second subdirectory ID belongs to the information of the subdirectory, and the second file ID belongs to the information of the file.
In the embodiment of the present invention, the information of the subdirectory includes, but is not limited to, a name, a size, a creation date, a storage path, a second subdirectory ID of the subdirectory, and the like of the subdirectory. The information of the file includes, but is not limited to, the name, size, creation date, storage path, second file ID, etc. of the new file.
Step S206, the information of the subdirectory and the information of the file are sent to the external equipment.
In this embodiment of the present invention, after receiving the information of the sub-directory and the information of the file sent by the mobile terminal, the external device may display the information of the sub-directory and the information of the file in a directory to which a new file of the external device belongs.
According to the embodiment of the invention, when the file is newly added in the virtual file system of the mobile terminal, the query operation of the external equipment is triggered, and the subdirectory and the file which are to be displayed on the current display interface of the external equipment are queried, so that all subdirectories and files of the directory can be displayed under the directory of the newly built file in the external equipment, and the real-time refreshing of the external equipment is realized.
Referring to fig. 3, which is a schematic diagram of an implementation flow of a file processing method provided in the third embodiment of the present invention, where the file processing method is applied to a mobile terminal, as shown in the figure, the file processing method may include the following steps:
step S301, when detecting a new file of a magnetic disk of the mobile terminal, controlling the mobile terminal to update a virtual file system.
