As shown in fig. 1, the file processing system includes a mobile terminal 11 and an external device 12. The external device 12 refers to a device that can be connected to the mobile terminal 11 through an external interface on the mobile terminal 11, for example, a device connected through a USB. The mobile terminal 11 may be connected to the external device 12 through a USB, so that the mobile terminal 11 and the external device 12 are in a Media Transfer Protocol (MTP) connection mode, because MTP can be implemented on the USB.
The method and the device aim to realize real-time refreshing of the external equipment when a new file is created on the mobile terminal. In the embodiment of the application, when detecting that a new file is added to a magnetic disk of a mobile terminal and the mobile terminal 11 and an external device 12 are in a Media Transfer Protocol (MTP) connection mode, the mobile terminal 11 acquires information of the new file; acquiring a second directory ID of the newly added file according to the first directory ID of the newly added file in the information of the newly added file; storing the information of the newly added file to a second directory of the newly added file in the virtual file system; the mobile terminal 11 receives the display request information sent by the external device 12; if the directory ID in the display request information is the second directory ID of the newly added file, the information of the newly added file stored in the virtual file system is sent to the external device 12.
The first directory ID of the newly added file is the ID of the directory of the newly added file in the magnetic disk of the mobile terminal, the second directory ID of the newly added file is the ID of the directory of the newly added file in the virtual file system of the mobile terminal, and the virtual file system is a database mapped by traversing the magnetic disk of the mobile terminal.
Optionally, the mobile terminal 11 uses a sum of the first directory ID of the newly added file and the first preset offset as the second directory ID of the newly added file.
Optionally, the mobile terminal 11 obtains a second file ID of the newly added file according to the first file ID of the newly added file in the information of the newly added file, where the first file ID of the newly added file is an ID of the newly added file in a magnetic disk of the mobile terminal, the second file ID of the newly added file is an ID of the newly added file in the virtual file system, and the second file ID of the newly added file in the virtual file system corresponds to at least one second directory ID.
Optionally, the mobile terminal 11 uses a sum of the first file ID of the newly added file and a second preset offset as the second file ID of the newly added file.
Optionally, the mobile terminal 11 sends, to the external device 12, request information for acquiring a directory ID of a current display interface of the external device 12.
Referring to fig. 2, which is a schematic view of an implementation flow of a file processing method provided in the second embodiment of the present application, 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 a new file of a magnetic disk of a mobile terminal and the mobile terminal and an external device are in a Media Transfer Protocol (MTP) connection mode, acquiring information of the new file.
In the embodiment of the application, when the mobile terminal detects that a new file is added in a magnetic disk of the mobile terminal and the external device are in an MTP (multiple time transfer protocol) connection mode, the mobile terminal is driven by the MTP to update the virtual file system, so that the information of the new file is stored in the virtual file system. The information of the new file includes, but is not limited to, a name, a size, a creation date, a storage path, a first directory ID, a first file ID, and the like of the new file. And the first directory ID of the newly added file is the ID of the directory of the newly added file in the magnetic 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 magnetic disk of the mobile terminal.
When the MTP connection is established between the mobile terminal and the external equipment, the external equipment can check 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. Wherein the virtual file system is a database mapped by traversing a disk of the mobile terminal.
Step S202, a second directory ID of the newly added file is obtained according to the first directory ID of the newly added file in the information of the newly added file.
And the second directory ID of the newly added file is the ID of the directory of the newly added file in a virtual file system of the mobile terminal, and the virtual file system is a database mapped by traversing a magnetic disk 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 first file ID) and the file ID of the file in the virtual file system (i.e., the second 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 first directory ID) and the directory ID of the file in the virtual file system (i.e., the second directory ID) may be set to be different.
Step S203, storing the information of the newly added file to a second directory of the newly added file in the virtual file system of the mobile terminal.
In this embodiment of the application, after the mobile terminal performs step S202, the mobile terminal may first detect whether the information of the new file exists in the virtual file system, and if so, no subsequent operation is performed; if not, go to step S203.
Detecting whether the information of the newly added file exists in the virtual file system may be to detect whether the information of the newly added file exists in a directory of which the ID is a second directory ID of the newly added file in the virtual file system, and if so, determining that the information of the newly added file exists in the virtual file system, and not executing subsequent operations; if not, determining that the information of the newly added file does not exist in the virtual file system.
In this embodiment of the application, since the directory ID (first directory ID) and the file ID (first file ID) of the newly added file in the magnetic disk of the mobile terminal are different from the directory ID (second directory ID) and the file ID (second file ID) in the virtual file system, when the information of the newly added file is stored in the directory of the virtual file system whose ID is the second directory ID of the newly added file, the information of the newly added file may be updated at the same time, for example, the first directory ID of the newly added file in the information of the newly added file may be modified to the second directory ID of the newly added file, the first file ID of the newly added file is modified to the second file ID of the newly added file, and the storage path of the newly added file is modified to the storage path in the virtual file system. Other information in the information of the newly added file, such as the name, size, creation date, and the like of the newly added file, may be kept unchanged.
Step S204, receiving display request information, wherein the display request information is sent by the external device.
In this embodiment of the application, after storing information of a newly added file in a directory whose ID is a second directory ID of the newly added file in the virtual file system, the mobile terminal sends request information for acquiring the directory ID of the current display interface of the external device to the external device, and after receiving the request information, the external device feeds back display request information including the directory ID of the current display interface of the external device to the mobile terminal. The directory ID of the current display interface of the external device may refer to the directory ID of the current display interface when the external device views the file in the mobile terminal.
Step S205, if the directory ID in the display request information is the second directory ID of the newly added file, sending the information of the newly added file stored in the virtual file system to the external device.
In the embodiment of the application, whether the directory ID in the display request information is the second directory ID of the newly added file is detected, if yes, the information of the newly added file is obtained from the virtual file system and sent to the external device, and after the external device receives the information of the newly added file, the information of the newly added file is displayed on a current display interface; and if not, not sending the information of the newly added file to the external equipment, and if subsequently receiving display request information containing the same second directory ID of the newly added file, then sending the information of the newly added file to the external equipment.
According to the method and the device, when the file is newly added to the magnetic disk of the mobile terminal, the information of the newly added file is stored in the virtual file system, and then the information of the newly added file stored in the virtual file system is sent to the external equipment, so that the information of the newly added file can be displayed in the second directory of the newly added file of the external equipment, and further, when the file is newly built on the mobile terminal, the real-time refreshing of the external equipment is realized.

Step S302, taking a sum of a first directory ID of the newly added file and a first preset offset in the information of the newly added file as a second directory ID of the newly added file.
The first directory ID of the newly added file is the ID of the directory of the newly added file in the magnetic disk of the mobile terminal, the second directory ID of the newly added file is the ID of the directory of the newly added file in the virtual file system of the mobile terminal, and the virtual file system is a database mapped by traversing the magnetic disk of the mobile terminal.
Optionally, the embodiment of the present application further includes:
and acquiring a second file ID of the newly added file according to the first file ID of the newly added file in the information of the newly added file, wherein the first file ID of the newly added file is the ID of the newly added file in a magnetic disk of the mobile terminal, the second file ID of the newly added file is the ID of the newly added file in the virtual file system, and the second file ID of the newly added file in the virtual file system corresponds to at least one second 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 application may map the file ID (i.e., the second file ID) of the newly added file in the virtual file system to a plurality of directory IDs (i.e., the second directory ID) when the file in the magnetic disk of the mobile terminal is mapped into the virtual file system.
Optionally, the obtaining the second file ID of the newly added file according to the first file ID of the newly added file in the information of the newly added file includes:
and taking the sum of the first file ID of the newly added file and a second preset offset as a second file ID of the newly added file.
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 first file ID) and the file ID of the file in the virtual file system (i.e., the second 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 first directory ID) and the directory ID of the file in the virtual file system (i.e., the second directory ID) may be set to be different.
In order to distinguish the directory to which the newly added file belongs in the magnetic disk of the mobile terminal from the directory to which the newly added file belongs in the virtual file system, the sum of the ID of the directory to which the newly added file belongs in the magnetic disk of the mobile terminal and a first preset offset may be used as the ID of the directory to which the newly added file belongs in the virtual file system. In order to distinguish whether the newly added file is in the magnetic disk of the mobile terminal or the virtual file system, the sum of the ID of the newly added file in the magnetic disk of the mobile terminal (i.e., the first file ID) and a second preset offset may be used as the ID of the newly added file in the virtual file system (i.e., the second file ID).
Step S303, storing the information of the newly added file to a second directory of the newly added file in a virtual file system of the mobile terminal.
The step is the same as step S203, and reference may be specifically made to the related description of step S203, which is not repeated herein.
Step S304, sending request information for acquiring the directory ID of the current display interface of the external device to the external device.
In step S305, display request information is received.
In this embodiment of the application, after storing information of a newly added file in a directory whose ID is a second directory ID of the newly added file in the virtual file system, the mobile terminal sends request information for acquiring the directory ID of the current display interface of the external device to the external device, and after receiving the request information, the external device feeds back display request information including the directory ID of the current display interface of the external device to the mobile terminal. The directory ID of the current display interface of the external device may refer to the directory ID of the current display interface when the external device views the file in the mobile terminal.
Step S306, if the directory ID in the display request information is the second directory ID of the newly added file, sending the information of the newly added file stored in the virtual file system to the external device.
The step is the same as step S205, and reference may be made to the related description of step S205, which is not repeated herein.
According to the method and the device, when the file is newly added to the magnetic disk of the mobile terminal, the information of the newly added file is stored in the virtual file system, and then the information of the newly added file stored in the virtual file system is sent to the external equipment, so that the information of the newly added file can be displayed in the second directory of the newly added file of the external equipment, and further, when the file is newly built on the mobile terminal, the real-time refreshing of the external equipment is realized. And the second file ID of the newly added file corresponds to at least one second directory ID in the virtual file system, so that the newly added file can be displayed in different directories in the external equipment.
