Description
Technical Field
The present invention relates to file management technologies, and in particular, to a method and an apparatus for managing files in a device with an operating system.
Background
As is well known, devices (hereinafter, a device in which an operating system is installed will be simply referred to as a device for convenience of description) such as a mobile terminal, a tablet computer, a computer, and the like, which are installed with operating systems such as a Windows (Windows) operating system of microsoft corporation, an Android (Android) operating system of google corporation, an apple phone operating system (iOS) of apple corporation, and the like, are widely used in various fields of production and life. In these devices, it is often necessary to store a large number of files, and file management becomes a fundamental function that various operating systems must provide. The operating system typically manages and displays the file directories in a file tree structure that is maintained by the operating system through a file index table on a memory of the device, such as a hard disk. In order to improve the efficiency and flexibility of file management, various file management software running on an operating system is pushed to the market.
Currently, the file management software on the market generally provides the related functions of file management by reading the file index table to display the tree structure of the file. These functions typically include: displaying all directories and files under any directory in the file tree structure, displaying file attributes of the selected files such as file size, modification date, type and the like, and displaying files of which the file attributes contain keywords for screening set by a user in all files under the file tree structure when the user starts global screening based on the file attributes. At present, when the file management software in the market provides the above functions, the file index table needs to be read once or more than once, and for some advanced file management functions such as global screening based on file attributes, the file attributes in the file header of the corresponding file in the memory need to be read according to the position information of the file in the read file index table. It is obvious that, when providing the advanced function of file management, the existing file management software needs to access the file index table on the memory once or more than once and needs to access the file header on the memory for each file to acquire the file attribute, when needing to continuously access hundreds of files or even more, because a large amount of or even mass of access memory is needed and the access time of the memory is difficult to reduce by one order of magnitude, the access time of the memory becomes a main hindering factor for efficiently providing the advanced function of file management when the access amount is increased by one or more than one order of magnitude, so that the existing file management software is often efficient in providing the advanced function of file management, and affects the user experience of file management.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

Fig. 1 is a flowchart of a method for managing files in the device of the present invention, as shown in fig. 1, including:
step 101: when the equipment is started, the file attributes meeting a preset first statistical strategy in the file attributes of each file are obtained.
Wherein the first statistical strategy comprises: the main file information set in the memory of the device, the file attribute to be counted. The first statistical strategy requires that at least file locations, such as file path information, be included in the statistical file attributes.
The method specifically comprises the following steps: when the device is started, reading the file attributes of each file in the memory of the device according to a file index table provided by an operating system, and extracting the file attributes meeting a first statistical strategy from the read file attributes.
The specific implementation of this step is a routine technical means for those skilled in the art, and is not described herein again.
Step 102: and generating a File Identifier (FID) which uniquely represents the file for each file, and adding a file information subset containing the generated FID and the obtained file attribute in the main file information set.
Wherein generating the FID may include: the FID is generated by a coding method of sequential coding.
The specific implementation of adding the file information subset including the generated FID and the obtained file attribute to the main file information set may be implemented by using a database technology, which belongs to a conventional technical means of those skilled in the art and is not described herein again.
In one embodiment of the present invention, the master file information set stores the tree structure of the files and the file attributes of each file, so that efficient file management can be achieved through the master file information set.
Further, the air conditioner is provided with a fan,

Wherein the second statistical strategy comprises: one or more file attributes to be counted from the file information set in the memory of the device.
Accordingly, the number of the first and second electrodes,
after generating the FID uniquely representing the file, the method of the present invention may further comprise the steps of: for each file, a subset of file information containing the generated FID and the obtained file attributes is added from the file information set.
In embodiment 1 of the present invention, the file information subset in the master file information set includes an FID and a file location, the file information subset in the slave file information set 1 includes an FID, a file name, and an extension, the file information subset in the slave file information set 2 includes an FID, a modification type, a time, and additional information, and the file information subset in the slave file information set 3 includes an FID, a file type, and a name of an application program that opened a file last time.
The modification type in the file information subset in the file information set 2 may be new creation or modification, the time may be time corresponding to the new creation or modification of the file, and the additional information may be a main body of the new creation or modification of the file, for example, the main body may be system generation, bluetooth transmission, or wireless local area network transmission; the file type from the subset of file information in the file information set 3 may be a text file or a picture file, etc.
In the above embodiment, it is obvious that each file attribute counted from the file information set has a correlation, and this way of putting the correlated file attributes into a statistics from the file information set according to the second statistical policy can improve the efficiency of managing the file attributes.
It will be understood by those skilled in the art that the subset of file information in the master and slave file information sets corresponding to the same file contain the same FID, and thus, they are correlated by the FID.
Further, in the method of the present invention as shown in fig. 1, the following 2 steps may also be included:
1) when a broadcast message informing file attribute updating is detected, determining a file information subset to be updated in the main file information set according to updating contents extracted from the broadcast message and the first statistical strategy;
2) and updating the file attribute corresponding to the extracted updated content in the determined file information subset.

2) And updating the file attribute corresponding to the extracted updated content in the determined file information subset.
It should be noted that the method of the present invention may further include a processing procedure when detecting a broadcast message notifying the addition/deletion of the file. The processing flow is similar to the processing flow when the method of the present invention detects the broadcast message notifying the update of the file attribute, and on the basis of updating the related processing flow, a person skilled in the art can easily implement the related processing flow of adding/deleting, and details are not repeated here.
Compared with the file management software on the market at present, the method can more efficiently realize the common functions of file management, such as displaying the file attributes of the selected files. When the method of the present invention is used to display the file attributes of the selected file, more file attributes can be efficiently displayed.
Compared with the file management software in the current market, the method can also realize the high-level functions of file management, such as global screening based on file attributes, and effectively improve the efficiency of providing the high-level functions of file management.
When a user wants to use global filtering based on file attributes, the user sets a directory for filtering and one or more keywords for filtering. In embodiment 1 of the present invention, it is assumed that the set keywords are: the time is within one day, the file type is a text file, and the extension name is doc.
Fig. 2 is a flowchart for implementing global screening based on file attributes in the embodiment of the present invention, and as shown in fig. 2, the flowchart includes:
step 201: when a file screening message is received, a sequence of file attribute groups is extracted from the file screening message, wherein the sequence of file attribute groups comprises one or more groups of file attributes.
Wherein, each group of file attributes comprises one or more file attributes counted in the same slave file information set.
In embodiment 1 of the present invention, it is assumed that the extracted file attribute group sequence is { (time: within one day), (file type: text file), (extension: doc) }, where the file attribute in the parentheses is a group of file attributes.
Step 202: determining a first slave file information set which is counted by the first group of file attributes according to a second statistical strategy aiming at the first group of file attributes in the file attribute group sequence; repeating the steps until an Nth slave file information set with an Nth group of file attributes is determined; where N is an integer having a value of the number of groupings of file attributes in the sequence of file attribute groups.
In embodiment 1 of the present invention, the first slave file information set is the slave file information set 2, the second slave file information set is the slave file information set 3, and the third slave file information set is the slave file information set 1.
Step 203: determining a first subset of file information of the set of file information that includes a first set of file attributes; for each FID in the determined subset of file information: setting M to be 2, reading a corresponding Mth file information subset in the slave file information set according to the current FID, and determining whether the read file information subset contains the Mth group of file attributes, wherein M is an integer which is greater than or equal to 2 and less than or equal to N; if the file information subset contains the M, adding 1 to the M, returning to execute reading the corresponding Mth file information subset in the slave file information set according to the current FID, and determining whether the read file information subset contains the Mth group of file attributes; if the file information is contained and M is equal to N, reading a file information subset in the corresponding main file information set according to the current FID, and determining the file corresponding to the current FID as a screened file; if not, the process for the current FID ends.
In embodiment 1 of the present invention, step 203 is executed to determine a file information subset in a master file information set and a slave file information set corresponding to each screened file whose file attribute satisfies { (time: within one day), (file type: text file), (extension: doc) }. As is easily realized by a person skilled in the art, the relevant information of the screened files, such as the names of the files, the positions of the files and the like, is displayed according to the file attributes in the determined file information subset.
It should be noted that, in embodiment 1 of the present invention, relevant file attributes are put into a slave file information set for statistics according to a second statistical policy, so that when performing global screening based on file attributes, it is possible to reduce accesses from the file information set as much as possible, thereby better improving access efficiency.
