in this embodiment, the storage object in the file system in S101 includes a file or a folder, and certainly includes data stored in the terminal in other forms, which is gradually generated in the process of using the system or various applications, and the longer the time is, the number and size of the file will increase, which will affect the running speed of the terminal.
In order to improve the accuracy of judging the garbage objects and fully utilize the existing data, the present embodiment analyzes the garbage degree of the storage objects based on the data indexes of various aspects of the storage objects in the file system, and of course, the data indexes of the storage objects are various and not all data are helpful for our judgment, so the present embodiment selects the target attribute data of the storage objects as the basis.
The target attribute data selected in this embodiment includes, but is not limited to: operation attribute data, size attribute data, and display state attribute data, the operation data including various data related to the operation of the storage object, such as data related to the type of the operation of the storage object, data related to the time of the operation of the storage object, and data related to the time interval of the operation of the storage object; the size attribute data includes data related to the size of the storage object, such as the size of the storage area where the storage object is located, the size of the area where the storage object is located, and the increment of the size of the storage object in a certain period of time, and if the storage object is a folder, the size attribute data also includes the number of subfiles of the folder; the display state attribute data is data related to various display states of the storage object, such as an originator of the storage object, a format of the storage object (being a file/folder), whether the storage object is readable, whether the storage object is writable, whether the storage object is display/hidden, and the like.
Correspondingly, the elements set according to the target attribute data in S101 include: the operation attribute elements set according to the operation attribute data, the size attribute elements set according to the size attribute data, and the status display elements set according to the display status attribute data, but the above three elements cannot be individually selected and used for making a spam file judgment policy to judge spam files.
Preferably, the operation attribute elements and/or the size attribute elements are/is selected as basic elements to formulate a garbage strategy, and when the storage object element set comprises the operation attribute elements, the matching condition comprises: whether the actual value of the operation attribute element is matched with the threshold value of the operation attribute element or not;
when the storage object element set comprises the size attribute elements, the matching condition comprises the following steps: what the size attribute element is whether the actual value matches the threshold value of the size attribute element.
The operation attribute elements of the embodiment include an operation type element, an operation time element, and an operation time interval element, where the operation type element includes all operation actions of the monitored file, such as deleting, creating, moving, copying, opening, modifying, and modifying readable and writable rights; the operation time pressure element includes times corresponding to the above-described various operations, such as a time of creating a file, a time of modifying a file, and the like; the operation time interval element may be regarded as a time period derived from the operation time, such as a time interval between the last modification time and the current time, a time interval between the last file opening and the current time, and the like.
After the elements are selected, a junk file judgment strategy can be set according to the threshold values of the elements, the selected elements are the time, the threshold values are numerical values related to the time, the selected elements are operation types, the threshold values are a specific operation type, and the junk strategy customized according to the operation attribute elements comprises the following modes:
firstly, selecting the operation type element, and setting the junk file judgment policy to judge a certain file as a junk file when detecting that the type of an operation performed on the certain file is deletion.
Selecting an operation time element, wherein the junk file judgment policy can be set to judge that a certain operation time of a certain file is before a certain time point, and the specific setting can be that the file is judged to be a junk file when the modification time of the file is before No. 8/8 of 2015. The above matching means that if the actual modification time of the file is No. 8/6 in 2015, the actual value of the modification time of the file is matched with the threshold value of the modification time in the garbage file judgment policy.
Selecting an operation time interval element, wherein the junk file judgment strategy can be limited to a certain operation time interval of a certain file from the current maximum time interval, and the file is judged to be a junk file when the operation time interval exceeds the interval, and the specific setting can be that the file is judged to be a junk file when the last time of access of the file exceeds the current time length by 10 days, or the file is judged to be a junk file when the effective activity time of an owner of the file is less than 30s within one week of the current time. .
And fourthly, selecting at least two elements of the operation type element, the operation time element and the operation time interval element to set garbage judgment processing, and judging that the file is a garbage file if the modification time of the file is all before No. 8/8 in 2015 and the last access time of the file is more than 10 days from the current time length.
The size attribute element of this embodiment includes a current size element of the storage object, a size variation element of the storage object, a size element of the storage area where the storage object is located, and the like, where the current size element of the storage object includes the size of the storage object, and if the storage object is a folder, the element refers to the entire size of the folder; the storage object size variation element comprises the size variation amount of the storage object in a certain period of time, and can be an increment or a difference; the size element of the storage area in which the storage object is located includes the total size of the storage area in which the storage object is located, and the threshold value set corresponding to the size element is a numerical condition that a certain size or a change amount of the size satisfies.
In the above-mentioned several size attribute elements, the garbage file is judged only by combining the general garbage judgment condition set according to the size element of the storage area where the storage object is located and the garbage judgment condition formulated according to other elements, and the garbage customization policy formulated according to the above-mentioned size attribute elements includes the following modes:
firstly, selecting the current size element of the storage object, wherein the junk file judgment strategy can be as follows: the cumulative write size of a single file exceeds 1G, or the overall size of the folder exceeds 800M, and the like.
Secondly, storing the size variable quantity elements of the object, wherein the junk file judgment strategy can be set as follows: if the size change of the stored object exceeds a certain value within a certain period of time, determining that the file is a junk file, specifically, if the increment of the file exceeds 300M within 7 days according to the current time, determining that the file is possibly a junk file. The above matching means that if the actual size of the file is increased by 200M within 7 days from the current time, the actual value of the storage object size variation element of the file does not match the threshold value of the storage object size variation element in the garbage file determination policy.
Thirdly, selecting any one of the current size element and the size variation element of the storage object or fully selecting the current size element and the size variation element of the storage object, setting a garbage file judgment strategy by combining the selected size element and the size element of the storage area where the storage object is located,
if the accumulated writing size of a single file exceeds 1G, the residual space of the partition where the file is located is less than 10%, and the size of the file occupies top 10 in the partition, judging that the file is a junk file;
or within 7 weeks from the current time, the increment of a certain file exceeds 300M, the residual space of the partition where the file is located is less than 10%, the size of the file occupies top 10 in the partition, and the file is judged to be a junk file;
or within the current 7 weeks, the increment of a certain file exceeds 300M, the cumulative writing size of the file exceeds 1G, the residual space of the partition where the file is located is less than 10%, the size of the file occupies top 10 in the partition, and the file is judged to be a junk file.
When the storage object element set of this embodiment includes the status display element, the matching condition includes: whether the actual value of the display status element matches the threshold value of the display status element.
The status display element of the present embodiment includes a format element indicating whether the storage object is a file or a folder; a readable attribute element indicating whether the document is readable; a writable attribute element indicating whether the file is writable; an originator element indicating an originator of the storage object; and a display/hide element indicating whether the storage object is in a hidden or displayed state.
The customized garbage strategy manufactured according to the state display element comprises the following modes:
one, only the format elements are selected, and the strategy is set that the storage object is a file or the storage object is a folder.
And secondly, only selecting the readable attribute elements or the writable attribute elements, and setting the strategy to be that the storage object can be read or the storage object can be written, wherein the file can be a junk file.
And thirdly, only selecting the originator elements, and setting the strategy that the originator of the storage object is an application or system which is easy to generate garbage, for example, the file originator is an application which is easy to generate garbage, such as QQ, WeChat, microblog and the like. The above matching means that if the originator of the document is a QQ, the actual values of the originator elements of the document match the threshold values of the originator elements in the spam determination policy.
And fourthly, only selecting the display/hidden elements, and setting the strategy that if the file or the folder is a hidden file, the file or the folder is not judged to be a junk file.
And fifthly, the garbage file judgment strategies set according to the four state display elements can be selected to be combined randomly to obtain a new garbage file judgment strategy.
The above is based on three major categories: the operation attribute elements, the size attribute elements and the state display elements can be combined into a new junk file judgment strategy at will, but the junk file judgment strategy made according to the state display elements needs to be used together with the junk file judgment strategy made according to other elements.
The junk file determination policy made according to the operation attribute element and the size attribute element may be a set of junk determination conditions set according to the respective sub-elements, for example, when the read-write time interval of a certain file currently exceeds 7 days or more, the cumulative write size of the file reaches or exceeds 1GB or more, and the time for the owner (application or system) of the file to effectively act within one week is less than or equal to 30s, the file is determined to be a junk file.
The junk file judgment policy made according to the operation attribute elements and the state display elements may be that the last operation time of a certain file is before 10 months and 30 th, the read-write time interval of the file currently exceeds more than 7 days, and the file is a non-hidden file, and the file is judged to be a junk file.
The strategy for judging the junk files specified by the three major elements can be as follows: the last operation time of a certain file is before No. 30 of 10 months; and the size of the file exceeds 1G; and the residual space of the partition where the file is located is less than 10%; and the increment of the file in one week exceeds 800M.
Of course, besides the above attribute data, the elements of the present embodiment may be set according to other data available for data mining.
If the spam file judgment policy is set in the above manner, more than one selected element is selected, and more than one spam file judgment policy is set, and it is possible that for a certain storage object, the actual values of all the elements do not match the threshold values of the elements in the spam file judgment policy, but only a part of the elements are matched, then a judgment rule may be set again, and the spam file is judged according to the actual matching condition, where the judgment rule may be that the storage object element set has elements whose actual values match the threshold values of the corresponding elements in the spam file judgment policy, and of course, these elements must include at least one of the above-mentioned operation attribute elements and size attribute elements, and the number of the matched elements is greater than a preset certain number value, and the storage object is judged to be a spam file. For example, the selected elements are an operation time interval element, an operation time element, a storage object current size element and a display state element, and the junk file judgment policy set according to the elements is as follows: 1. the last time of file access is more than 10 days from the current time, 2, the size of the file is more than 1G, 3, the originator of the storage object is an application or system which is easy to generate garbage, for example, the originator of the file is an application which is easy to generate garbage, such as QQ, WeChat, microblog and the like, and 4, the modification time of the file is all before No. 8/8 in 2015. The determination rule may be set such that the actual value of an element in the storage object element set matches at least the threshold value of an element in policy 1, or the actual value of an element in the storage object element set matches at least the threshold value of an element in policy 2, and on the basis that the number of matched elements in the storage object element set exceeds 2, the storage object is determined to be a junk file.
In this embodiment, the spam file determining policy set in S101 may be preset on the terminal, so S101 may also directly obtain a preset spam file determining policy.
The attribute data of the storage objects on different terminals are different, so that different users may have different requirements on the junk file judgment policy. In order to meet the requirements of users and improve the adaptability of the invention in different terminals, preferably, the implementation can receive a processing modification instruction sent by the user, and modify the junk file judgment policy according to the policy modification instruction.
Preferably, the policy modification instruction may be an element adjustment instruction for adjusting an element of the spam file determination policy or a threshold adjustment instruction; when the command is a component adjustment command, the components in the component set need to be updated, the updating of the components in the component set includes deleting or adding the components in the component set according to an updated component set updating strategy, the corresponding junk file judgment strategy is correspondingly deleted or added in the strategy, and when the current target attribute data of the storage object is acquired, the acquired target attribute data is correspondingly deleted or added along with the addition or deletion of the components. For example, when the element set deletes the size element of the storage area where the storage object is located, the determination policy for the junk file set according to the element in the determination policy is also deleted, and when the target attribute data of the storage object is obtained, the size data of the storage area where the storage object is located is not obtained.
The policy modification instruction may also be a threshold adjustment instruction for adjusting a threshold of an element of the spam file determination policy, the threshold of the corresponding element is updated according to the threshold adjustment instruction, and the policy is updated according to the updated threshold, for example, if the threshold adjustment instruction instructs to modify the threshold of the policy "the size of the file exceeds 1G" to 900M, the updated spam file determination policy "the size of the file exceeds 900M".
By adopting the junk file identification method of the embodiment, the original attribute data on the terminal is fully utilized, the element set comprising at least one element is set according to the attribute data, the junk file judgment strategy is set according to the elements, then the actual values of the elements are obtained on the basis of obtaining the current actual attribute data of the storage object, and whether the storage object is a junk file is judged according to the threshold matching condition of the corresponding element in the actual values and the junk file judgment strategy, so that the judgment method has good adaptability and higher judgment accuracy.
