Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Based on the above problems, embodiments of the present application provide a file scanning method, an apparatus, a computer-readable storage medium, and a terminal, which can effectively improve a file scanning rate. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.

Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a file scanning method according to an embodiment of the present disclosure. The file scanning method may be applied to mobile terminals such as mobile phones, tablet computers, notebook computers, palm top computers, Portable Media Players (PMPs), and fixed terminals such as desktop computers. The specific flow of the file scanning method can be as follows:

101. and receiving a file scanning request, and acquiring a file set according to the scanning request.

In this embodiment, the file scan request may be sent by the end system. The file scanning is to enter a file database by scanning file information, and to read and update data of a file. Wherein the file may be stored in a terminal memory and the file may be a media file. For example, the files may include media files such as pictures, music, and the like.

The file scanning request may be implemented in various ways. In some embodiments, the file scanning may be triggered by: when the terminal is detected to be switched from the power-off state to the power-on state, a file scanning instruction is triggered, and a scanning request is sent through the scanning instruction.

Specifically, when the terminal is in a power-off state, the user may perform a power-on operation on the terminal, and after the terminal is powered on, the system may send information for starting scanning, where the information may be sent in a broadcast manner.

For example, after the terminal completes the power-on operation, the system may send a broadcast, and the broadcast may be "intent. After receiving the broadcast information sent by the system, the file in the memory can be scanned. By executing the starting operation on the terminal and triggering the file scanning request, the storage content of the whole storage space can be scanned.

After receiving a file scan request, a file collection is obtained. Wherein the file collection may be a file library, which may be stored in a terminal memory. A collection of files may include multiple folders, for example, a collection of files may include folder A, folder B, folder C, and so on. Through the file scanning request, all folders in the terminal memory can be quickly acquired.

102. And dividing the files in the file set to obtain a plurality of sub-file sets.

In this embodiment, the files in the file set are divided, and there may be a plurality of dividing manners. For example, a collection of files may be divided by file name. The file sets are divided to obtain a plurality of subfile sets, so that the plurality of subfile sets can be conveniently scanned simultaneously, and time is saved.

In some embodiments, the step of "dividing files in a file collection" may include the following processes:

(11) acquiring file information of a file, wherein the file information at least comprises a file name;

(12) sorting the files according to the file names to obtain a third sorting result;

(13) and determining the number of the files, and dividing the files based on the number of the files and the sequencing result.

Specifically, after the file collection is obtained, the files in the file collection may be determined. Further, file information of the file is obtained, and the file information may include a file name, where the file name may be set by a user or default, for example, the user may create a new folder, and the folder name is set to be "picture". In order to conveniently and quickly search for the pictures, the user can add the pictures on the terminal to the picture folder for storage.

The file name may be a character string, and the character string may include numbers, letters, and words. For example, the file name may be set to: a123, file a, file B1, and so on. After the file names of all files are obtained, the initial of the file name is determined, for example, if the file name is: and A123, acquiring a letter of 'A', and if the file name is: file a, the obtained initial is "W", etc.

Specifically, after the first letters of all the file names are acquired, the files may be sorted according to the alphabetical order. For example, the alphabetical order may be: a-z, the first letters of the file names a-z may be ordered so that the result of the ranking of the files may be determined.

Further, after sorting the files, the number of files in the file collection is determined. For example, the number in a set of files may be 1, 2, 3, 10, and so on. Specifically, the file set is divided according to the sorting result and the number of the files.

When the file set is divided according to the sorting result and the number of the files, a plurality of dividing modes can be provided. In some embodiments, the step of "dividing the files based on the number of files and the sorting result" may include the following processes:

(131) comparing the number of files with the number of preset thread units;

(132) if the number of the files is smaller than the number of the preset thread units, dividing the file set into a subfile set with the number of the files, and determining the files in the subfile set according to a third sequencing result;

(133) and if the number of the files is greater than or equal to the number of the preset thread units, dividing the file set into sub-file sets with the number of the preset thread units, and determining the files in the sub-file sets according to a third sequencing result.

Specifically, the number of files in the file set is compared with the number of preset thread units. Wherein the thread unit may be configured to perform a scan operation on the matched file.

A thread is the smallest unit that an operating system can perform computational scheduling. It is included in the process and is the actual unit of operation in the process. A thread refers to a single sequential control flow in a process, multiple threads can be concurrently executed in a process, and each thread executes different tasks in parallel. The thread is used, tasks in the program which occupy a long time can be put into the background to be processed, and the running speed of the program is improved.

The number of the preset thread units can be the number of the divisible optimal threads, namely when a plurality of thread units of the number of the preset thread units work simultaneously, the working efficiency is not influenced mutually, and the working time can be effectively saved.

Comparing the number of the files with the number of the preset thread units, wherein the comparison result can comprise that the number of the files is greater than or equal to the number of the preset thread units, and the number of the files is less than the number of the preset thread units.

For example, the number of the preset thread units may be 5, the number of the files may be 8, and the number of the files is compared with the number of the preset thread units to obtain a comparison result: the number of the files is larger than or equal to the number of the preset thread units. The file set may be divided into 5, resulting in 5 sub-file sets.

After the number of the sub-file sets is determined, the files can be divided into the sub-file sets according to the sorting result of the files in the file sets. The dividing manner may be various, for example, the number of the subfile sets may be 5, and the subfile sets may be named A, B, C, D, E respectively. The number of files in the file set can be 8, and the files can be a, b, c, d, e, f, g and h according to the sorting result. File a may be divided into subset a, file B may be divided into subset B, file C may be divided into subset C, file D may be divided into subset D, file E may be divided into subset E, file f may be divided into subset a, file g may be divided into subset B, and file h may be divided into subset C.

For another example, the number of the preset thread units may be 5, the number of the files may be 3, and the number of the files is compared with the number of the preset thread units to obtain a comparison result: the file number is larger than the number of the preset thread units. The file set may be divided into 3 resulting in 3 sub-file sets.

After the number of the sub-file sets is determined, the files can be divided into the sub-file sets according to the sorting result of the files in the file sets. The dividing manner may be various, for example, the number of the subfile sets may be 3, and the subfile sets may be named as AA, BB, and CC, respectively. The number of files in the file set can be 3, and the number can be aa, bb and cc according to the sorting result. File AA may be partitioned into subset AA, file BB into subset BB, and file CC into subset CC. The file set is divided into the plurality of sub-sets, and the files in the file set are divided according to the preset sequence, so that the plurality of files can be processed simultaneously, and the working efficiency of the processor is improved.

103. And matching target thread units for the subfile sets, wherein the target thread units correspond to the subfile sets one by one.

In some embodiments, the step "matching target thread units for subfile sets" may include the following flows:

(21) determining the number of the sub-file sets;

(22) dividing the number of thread units according to the number;

(23) a target thread unit is determined based on the thread units and matched for the set of subfiles.

Specifically, after the number of the subfile sets is determined, the same number of thread units may be divided by the number of the subfile sets. For example, the number of subfile sets may be 3, and 3 thread units may be divided.

After the number of thread units is determined, one thread unit can be selected from the plurality of thread units as a target thread unit, and a subfile set can be matched for the target thread unit. The matching method may include multiple methods.

Specifically, the matching manner may be to determine a correspondence between the thread unit and the subfile set, and sort according to the correspondence. In some embodiments, the step of "determining a target thread unit based on the thread units and matching the target thread unit for the subfile set" may comprise the flow of:

(2311) sequencing the thread units to obtain a first sequencing result;

(2312) sequencing the sub-file sets to obtain a second sequencing result;

(2313) determining the corresponding relation between the first sequencing result and the second sequencing result;

(2314) and matching the corresponding target thread unit for the target subfile set according to the corresponding relation.

Specifically, the thread units are sequenced to obtain a first sequencing result. The thread units can be sorted according to the names of the thread units, and the names of the thread units can be numbers. For example, if the number of thread units is 5, the names of the 5 thread units may be: ccc, aaa, bbb, eee, ddd. Sorting according to the names can obtain a sorting result as follows: aaa, bbb, ccc, ddd, eee.

Specifically, the subfile sets are sorted to obtain a second sorting result. The sub-file sets can be sorted according to names of the sub-file sets, and names of the sub-file sets can be numbers. For example, if the number of the sub-file sets is 5, the names of the 5 sub-file sets may be: b. d, c, a, e. Sorting according to the names can obtain a sorting result as follows: a. b, c, d, e.

After the sorting result of the thread unit and the sorting result of the subfile set are determined, the corresponding relationship can be determined according to the sorting result of the thread unit and the sorting result of the subfile set.

For example, the ordering result of a thread unit may be: aaa, bbb, ccc, ddd, eee; the sorting result of the sub-file set may be a, b, c, d, e. Then the correspondence may be determined as: the thread unit aaa may correspond to the subfile set a, the thread unit bbb may correspond to the subfile set b, the thread unit ccc may correspond to the subfile set c, the thread unit ddd may correspond to the subfile set d, and the thread unit eee may correspond to the subfile set e. By acquiring the names of the thread units and the subfile sets and sequencing according to the names, a subfile set corresponding to each thread unit can be quickly determined.

In some embodiments, the step of "determining a target thread unit based on the thread units and matching the target thread unit for the subfile set" may comprise the following flows:

(2321) acquiring the processing rate of a thread unit;

(2322) acquiring the storage capacity occupied by the subfile set;

(2323) and matching the corresponding target thread unit for the subfile set according to the processing rate and the storage capacity.

Specifically, the processing rate of the thread unit is obtained, and the processing rate may be the file scanning capability of the thread unit.

The processing rate may be set for the thread unit when the thread unit is divided, for example, the thread unit may include a thread unit a, a thread unit b, and the like, and when the thread unit a is set, the processing rate of the thread unit a may be set to 10kb/s, and the processing rate of the thread unit b may be set to 8 kb/s.

After determining the processing rates of all thread units, all thread units are ordered based on the processing rates. There may be multiple ordering modes when ordering thread units. For example, the processing rates may be arranged in order from high to low. For example, if the thread units include a thread unit a with a processing rate of 10kb/s and a thread unit b with a processing rate of 8kb/s, the ordering result of the thread units can be determined as follows: thread unit a and thread unit b.

Specifically, the storage capacity occupied by the subfile set is obtained, and the storage capacity occupied by the subfile set is the memory space occupied by the subfile set in the terminal memory. For example, the subfile set may include a subfile set a, a subfile set B, and the like, the memory size of the subfile set a may be 1M, and the memory size of the subfile set B may be 2M.

And after the storage capacity occupied by all the subfile sets is obtained, sequencing the subfile sets based on the storage capacity. When sorting the set of sub-files, there may be a variety of sorting approaches. For example, the storage capacities of the subfile sets may be arranged in descending order. For example, the subfile set may include a subfile set a with a memory size of 1M and a subfile set B with a memory size of 2M, and the sorting result of the subfile set may be determined as follows: subfile set B, subfile set A.

After the sorting result of the thread unit and the sorting result of the subfile set are determined, the corresponding target thread unit can be matched for the subfile set according to the corresponding relation between the sorting result of the thread unit and the sorting result of the subfile set. For example, the ordering result of a thread unit may be: the thread unit a and the thread unit b, and the sorting result of the subfile set may be: the subfile set B and the subfile set A can be matched with the thread unit a for the subfile set B; thread unit b is matched for subfile set a.

Different subfile sets are processed according to the processing capacity of the thread unit, the maximum subfile set is processed by the fastest thread unit, and the processing speed of the thread unit can be improved.

104. A corresponding set of subfiles is scanned on a per target thread unit basis.

Specifically, after each thread unit is matched with each subfile set in the above manner, it can be determined that each thread unit corresponds to one subfile set. Wherein, a plurality of threads start to execute scanning operation at the same time, and each thread unit scans the subfile set matched with the thread unit.

For example, the thread unit aa may correspond to a subfile set a, which may include a file q, a file w, and a file e; the thread unit bb can correspond to a subfile set B, and the subfile set B can correspond to a file y and a file u; the thread unit cc may correspond to a subfile set C, which may include file g, file h, file j, etc. Specifically, after starting the file scanning operation, the thread processing unit aa scans the file q, the file w, and the file e; the thread processing unit bb scans the file y and the file u; the thread processing unit cc processes the file g, the file h, the file j, etc.

By starting the multiple threads and executing corresponding operations by the multiple threads at the same time, parallel processing scanning can be achieved, traversing scanning speed is increased, and updating speed of the media database is increased.

According to the scheme, a file scanning request is received, a file set is obtained according to the scanning request, files in the file set are divided, a plurality of subfile sets are obtained, the subfile sets are matched with target thread units, the target thread units correspond to the subfile sets one to one, and the corresponding subfile sets are scanned on the basis of each target thread unit. According to the scheme, the plurality of threads are divided, the scanning file is started simultaneously according to the plurality of threads, the processor is used for executing the scanning operation to the maximum extent, the file scanning time is saved, and the file scanning speed can be effectively improved.

After the terminal is turned on, that is, when the terminal is switched from the power-off state to the power-on state, the system automatically sends information for starting scanning, for example, the information may be an intent broadcast, the broadcast content may be "intent. At this time, the terminal is triggered to receive the file scanning request, and the terminal can start scanning the file in the memory.

202. And the terminal acquires the file set according to the file scanning request.
