the method comprises the steps of traversing each physical file in the mobile terminal, distributing a file number to each physical file in the mobile terminal, writing the file number into index information of the corresponding physical file, distributing the file number to each physical file in the mobile terminal, traversing each physical file in the mobile terminal again to obtain the index information of each physical file, wherein the index information comprises the file number and a physical storage path.
In this embodiment, the rule that a file number is allocated to each physical file in the mobile terminal is that the mobile terminal traverses each physical file, and allocates a positive integer to the physical file obtained by traversing from 1 in sequence, where the allocated positive integer is the file number, for example, if the physical file traversed for the first time is a picture, the file number allocated to the picture is 1, and if the physical file traversed for the second time is a document, the file number allocated to the document is 2, and so on until the physical files in the mobile terminal are all allocated with file numbers. In a specific implementation, when assigning a file number to a physical file in a mobile terminal, the file number may be further assigned based on the file type of the physical file, specifically, the number of the physical file of each file type is calculated, then a file number set is assigned to the physical file of each file type based on the number of the physical file of each file type and the assignment sequence of each file type, that is, each file type corresponds to a file number set, and finally a file number is assigned to the physical file of the corresponding file type based on the file number set of each file type, for example, if the file types are a picture type, a music type, and a document type, and the corresponding file numbers are 5, 7, and 4, and if the assignment sequence is a picture type, a music type, and a document type, the file number set assigned to the physical file of the picture type is [1, 2, 3, 4, 5], and the file number set assigned to the physical file of the music type is [6, 2, 3, 4, 5], 7. 8, 9, 10, 11, 12], and the set of file numbers assigned to the document class physical files is [13, 14, 15, 16 ].
Step S1012, acquiring a file number and a physical storage path of a corresponding physical file from the index information of each physical file;
step S1013, the file number of each physical file is associated and mapped with the physical storage path to establish a mapping relationship table between the file number of the mobile terminal and the physical storage path.
After the mobile terminal obtains the index information of each physical file in a traversing manner, the file number and the physical storage path of the corresponding physical file are obtained from the index information of each physical file, the file number and the physical storage path of each physical file are subjected to associated mapping, so that the mapping relation between the file number and the physical storage path of each physical file is determined, finally, a mapping relation table of the file number and the physical storage path of the mobile terminal is established based on the determined mapping relation between the file number and the physical storage path of each physical file, and the mapping relation table is stored in a local database.
Step S102, constructing a virtual file tree in the memory of the mobile terminal according to a preset file tree construction rule and a mapping relation table in the local database;
after the mobile terminal stores the mapping relation table in the local database, a virtual file tree is constructed in the memory of the mobile terminal according to the preset file tree construction rule and the mapping relation table in the local database. The preset file tree construction rule is that a user name of a mobile terminal is called a root node, each file type is used as a leaf node, and a physical file contained in each file type is used as a child node of the leaf node.
Specifically, referring to fig. 4, fig. 4 is a detailed flowchart of step S102 shown in fig. 2, where step S102 includes:
step S1021, constructing a virtual file classification tree in the memory of the mobile terminal according to a preset file tree construction rule, and determining classification characteristic information of each leaf node in the virtual file classification tree;
the mobile terminal constructs a virtual file classification tree in a memory of the mobile terminal according to a preset file tree construction rule, namely a user name of the mobile terminal is used as a root node, each file type is used as a leaf node, the virtual file classification tree is constructed in the memory of the mobile terminal, and classification characteristic information of each leaf node in the virtual file classification tree is determined, wherein the classification characteristic information comprises classification characteristics such as picture characteristics, music characteristics, document characteristics and video characteristics. In a specific implementation, the physical files in the mobile terminal may be classified based on different file classification rules, where the file classification rules include file format classification rules, file source classification rules, and file application classification rules, where the file format classification rules classify the physical files into pictures, music, videos, and documents based on the formats of the physical files, the file source classification rules classify the physical files into collections, downloads, and bluetooth transmissions based on the sources of the physical files, and the file application classification rules classify the physical files based on the applications to which the physical files belong, such as WeChat, Internet News, Canine, and short messages.
Step S1022, obtaining a physical storage path including the classification feature information from a mapping relationship table in the local database, and obtaining a file number corresponding to the physical storage path from the mapping relationship table;
and step S1023, using the file number as a child node of the corresponding leaf node to update the virtual file classification tree, and using the updated virtual file classification tree as a virtual file tree.
After the mobile terminal constructs a virtual file classification tree and determines the classification characteristic information of each leaf node in the virtual file classification tree, a physical storage path containing the classification characteristic information is obtained from a mapping relation table in a local database, a file number corresponding to the physical storage path is obtained from the mapping relation table, the file number is used as a child node of the corresponding leaf node to update the virtual file classification tree, and the updated virtual file classification tree is used as a virtual file tree. In this embodiment, the classification feature information includes a file extension name, application identification information, source identification information, and the like.
Step S103, calling a preset hash algorithm to process the file number of each tree node in the virtual file tree so as to establish a hash table of the virtual file tree;

In this embodiment, the step S103 includes:
acquiring the file number of each tree node in the virtual file tree;
calling a preset hash algorithm to process the file number of each tree node so as to obtain a corresponding hash address;
and establishing a hash table according to the file number of each tree node and the hash address corresponding to the file number.
The mobile terminal acquires the file number of each tree node in the virtual file tree, wherein the file numbers of the root node and the leaf node are null, and calls a preset hash algorithm to process the file number of each tree node so as to acquire a corresponding hash address, then establishes a hash table according to the file number of each tree node and the hash address corresponding to the file number, and stores the hash table in a memory of the mobile terminal. It should be noted that the predetermined hash algorithm may be set by a person skilled in the art based on actual situations, and this is not specifically described in this embodiment.
And step S104, when a file acquisition instruction sent by the PC terminal is monitored, transmitting the file number of each physical file to the PC terminal so that the PC terminal can display the files in the mobile terminal based on the file numbers, the hash table and the virtual file tree.

In a specific implementation, the establishing operation of the mapping relation table and the hash table and the establishing operation of the virtual file tree may be performed when the mobile terminal is connected with the PC terminal, or before the mobile terminal is connected with the PC terminal, if the establishing operation is performed before the mobile terminal is connected with the PC terminal, the establishing operation of the mapping relation table, the virtual file tree and the hash table is updated at preset intervals, and when the connection of the mobile terminal and the PC terminal is detected, whether the physical file is updated or not is determined on the basis of the established mapping relation table, the virtual file tree and the hash table, if the physical file is updated, the physical file is updated on the basis of the established mapping relation table, the virtual file tree and the hash table, and if the physical file is not updated, the file on the mobile terminal is displayed on the PC terminal on the basis of the establishing operation of the mapping relation table, the virtual file tree and the hash table.
In this embodiment, the present invention first establishes a mapping relationship table between file numbers and physical storage paths, constructs a virtual file tree based on the established mapping relationship table and file classification, then processes the file numbers of each tree node based on a hash algorithm, establishes a hash table of the virtual file tree, so that after a PC terminal is connected to a mobile terminal, the PC terminal can quickly query the file numbers of each child node in the virtual file tree from the hash table based on the file numbers of the physical files sent by the mobile terminal, and quickly acquire the physical storage paths of the files based on the file numbers of each child node, thereby displaying the files in the mobile terminal on the PC terminal in a file classification manner, greatly improving the file acquisition speed, reducing the user waiting time, and facilitating the user to quickly acquire the files in the mobile terminal.
