Build, it is mobile, replicate, open, change, readable write permission modification etc.；It is right that operating time pressure key element includes
Should be in the time of above-mentioned various operations, such as the time of establishment file, the time for changing file etc.；Operation
Time interval key element is considered as the time period being derived according to the operating time, such as last modification time distance
Duration interval that current duration is spaced, the time gap of last time opening file is current etc., will according to above-mentioned
, it is necessary to for corresponding key element sets threshold value, the threshold value of key element refers to choosing when element sets rubbish Rule of judgment
Key element meet condition, threshold value here can be not only certain specific numerical value, can also be expression certain
Plant the information of particular state.
Just garbage files determination strategy can be set according to the threshold value of key element after key element has been chosen, chosen
Key element be the above-mentioned time, then threshold value is exactly the numerical value relevant with the time, and the key element chosen is operation class
Type, threshold value is exactly certain specific action type, and rubbish strategy is determined according to above-mentioned operational attribute key element
Including following several ways：
First, action type key element, garbage files determination strategy is chosen to could be arranged to, when detecting to certain
The type of the operation that file is carried out is when deletion, this document to be judged into garbage files.
2nd, operating time key element, garbage files determination strategy is chosen to could be arranged to certain operation of certain file
Time before certain time point, judges that this document is garbage files, and specifically setting to be, file
Modification time is complete before August 8 in 2015, judges that this document is garbage files.What above-mentioned matching referred to
It is, if the actual modification time of this document is August 6 in 2015, the reality of the modification time of this document
Threshold value of the actual value just with the modification time in garbage files determination strategy is matched.
3rd, operating time spacing elements are chosen, garbage files determination strategy can be defined to certain of certain file
The current maximum time interval of operating distance, more than the interval, judges that this document is garbage files, specifically
Setting can be that the current duration of the time gap of file last visit judged that this document was rubbish more than 10 days
Rubbish file, it is also possible to set within tool current time one week, the Effective activity time of the owner of file is less than
30s, judges that this document is garbage files..
4th, at least two in selection operation Type elements, operating time key element, operating time spacing elements
Key element is gone to set rubbish judgement and is processed, and such as the modification time of file is complete before August 8 in 2015 and file
The current duration of the time gap of last visit judged that this document was garbage files more than 10 days.
The size attribute key element of the present embodiment includes the current size key element of storage object, storage object size variation
Size key element of memory block etc., the current size key element of above-mentioned storage object where amount key element and storage object
Size including storage object, if storage object is file, what the key element referred to is exactly the entirety of file
Size；Storage object size variation amount key element includes the amount of size variation of the storage object within certain time,
Can with or increment or residual quantity；Memory block where the size key element of storage area includes storage object where storage object
Total size in domain, the threshold value that correspondence is set with size key element is the variable quantity satisfaction of certain size or size
Value conditions.
In above-mentioned several size attribute key elements, only the size key element of memory block according to where storage object is set
Rubbish Rule of judgment generally require and the rubbish Rule of judgment combination formulated according to other key elements judges rubbish
File, the rubbish strategy of determining according to above-mentioned size attribute key element includes following several ways：
First, choosing the current size key element of storage object, garbage files determination strategy can be：Single file is tired out
Meter write-in size more than 1G, or file overall size more than 800M etc..
2nd, storage object size variation amount key element, garbage files determination strategy could be arranged to：Certain time
Memory storage object size variable quantity exceedes certain value, is judged to garbage files, can be specifically, works as in evidence
In 7 days preceding time, the increment of certain file judges that this document may be garbage files more than 300M.Above-mentioned
If matching refers to this document in the actual size increment 200M in current time 7 days, this article
The actual value of the storage object size variation amount key element of part is just big with storage object in garbage files determination strategy
The threshold value of small variable quantity key element is unmatched.
3rd, choose in the current size key element of storage object and storage object size variation amount key element any one or it is complete
Choosing, garbage files determination strategy is set with the size factor combination of storage object place storage area,
If the accumulative write-in size of single file is more than 1G, and file place subregion remaining space is less than 10%, and
This document size accounts for top 10 in the subregion, judges that this document is garbage files；
Or within current 7 weeks, the increment of certain file is more than subregion remaining space where 300M, and file not
Foot 10%, and this document size accounts for top 10 in the subregion, judges that this document is garbage files；
Or within current 7 weeks, the increment of certain file surpasses more than 300M, and the accumulative write-in size of this document
Subregion remaining space is less than 10% where crossing 1G, and this document, and this document size accounts for top 10 in the subregion,
Judge that this document is garbage files.
When the storage object key element collection of the present embodiment includes status display key element, match condition includes：Display shape
Whether the actual value of state key element matches with the threshold value of the dispaly state key element.
The status display key element of the present embodiment includes form key element, represents that storage object is file or file；
Attribute-readable key element, represents whether file is readable；Writeable attribute key element, represents whether file is writeable；It is original
Person's key element, represents the founder of storage object；Display/hide key element, represents that storage object is to hide or aobvious
Show state.
Rubbish strategy of determining according to above-mentioned status display key element includes following several ways：
First, form key element is only selected, strategy setting is that storage object is file or storage object is file.
2nd, attribute-readable key element or writeable attribute key element are only selected, strategy setting is that storage object is readable or deposits
Storage object is writeable, and file is probably garbage files.
3rd, founder's key element is only selected, strategy setting is that the founder of storage object is easily to produce rubbish
Using or system, such as file founder is that QQ, wechat, microblogging are also easy to produce the application of rubbish.Above-mentioned
If being QQ with the founder for referring to this document, the actual value of founder's key element of this document is just and rubbish
The threshold value of the founder's key element in rubbish file determination strategy is matching.
4th, only choosing shows/hiding key element, and strategy setting is that file or folder is hidden file, then will
File or folder is judged to garbage files.
5th, the above-mentioned garbage files determination strategy set according to above-mentioned four kinds of status display key elements can be selected
Any combination obtains new garbage files determination strategy.
It is above-mentioned according to three major types key element：Operational attribute key element, size attribute key element, status display key element, system
Fixed garbage files determination strategy can be optionally combined into new garbage files determination strategy, but should be noted
It is that the garbage files determination strategy formulated according to status display key element is wanted and according to the rubbish of other key elements formulation
File determination strategy is used together.
The garbage files determination strategy formulated according to operational attribute key element and size attribute key element can be according to each
From the set of rubbish Rule of judgment that sets of sub- key element, for example, the access time of certain file is away from present
More than more than 7 days, and the accumulative write-in size of this document met or exceeded this document in more than 1GB, and a week
Time of owner's (application or system) effectively activity be less than or equal to 30s, judge that this document is garbage files.
Can be according to the garbage files determination strategy that operational attribute key element and status display key element are formulated, certain text
The operating time of part last time, the access time of file alreadyd exceed 7 away from present before October No. 30
More than it, and file is non-hidden file, judges that this document is garbage files.
Can be according to the garbage files determination strategy that three big key elements are specified：During the operation of certain file last time
Between before October No. 30；And the size of file is more than 1G；And the remaining insufficient space of subregion where file
10%；And increment of the file in one week is more than 800M.
Certainly, in addition to above-mentioned attribute data, the present embodiment key element can also be available for data to dig according to other
The data of pick are set.
If garbage files determination strategy is set by above-mentioned mode, the key element more than one chosen, if
The garbage files determination strategy put is more than one, may be not every to want for certain storage object
The actual value of element all matches the threshold value of the key element in garbage files determination strategy, but can only match a part,
One judgment rule so at this time can be again set, garbage files are judged according to actual match condition,
The judgment rule can be that storage object key element is concentrated with the actual value of key element and garbage files determination strategy
The key element of the threshold value matching of correspondence key element, certainly, must include operational attribute mentioned above in these key elements
At least one in key element and size attribute key element, and the key element of matching number more than it is default certain each and every one
Numerical value, just judges that the storage object is garbage files.The key element for example chosen be operating time spacing elements,
The current size key element of operating time key element, storage object, dispaly state key element, are set according to these key elements
Garbage files determination strategy is：1st, the current duration of the time gap of file last visit is more than 10 days, 2,
The size of file more than 1G, 3, the founder of storage object be application or the system for easily producing rubbish, such as text
Part founder is the application that QQ, wechat, microblogging etc. are also easy to produce rubbish, 4, the modification time of file it is complete 2015
Year August 8 is before.Judgment rule could be arranged to, and the actual value of the key element that storage object key element is concentrated is extremely
The threshold value of few key element with strategy 1 is matched, or storage object key element concentration key element actual value at least with
The threshold value matching of the key element in strategy 2, on this basis, the key element of the matching that storage object key element is concentrated
Number judges that storage object is garbage files more than 2.
The garbage files determination strategy set in the present embodiment S101 can be set in advance in terminal, institute
Can also be the default garbage files determination strategy of direct access with S101.
The attribute data of the storage object on different terminals is not quite similar, so different users is to garbage files
The requirement of determination strategy might have difference.In order to meet the demand of user and improve the present invention in different terminals
Adaptability, it is preferable that the treatment modification instruction of user's transmission can be received in this implementation, according to using the plan
Slightly modification instruction is modified to garbage files determination strategy.
Preferably, strategy modification instruction can be adjusted for the key element to garbage files determination strategy
Key element adjust instruction or adjusting thresholds are instructed；, it is necessary to be concentrated to key element when instruction is key element adjust instruction
Key element is updated, and according to the key element collection more new strategy after renewal, the updated core elements that key element is concentrated is included,
The key element that key element is concentrated is deleted or increased, can correspondingly be deleted in strategy or be increased corresponding garbage files and sentenced
Disconnected strategy, and when the current objective attribute target attribute data of storage object are obtained, the objective attribute target attribute data of acquisition
Also there can be corresponding deletion or increase with the increase of key element or deletion.For example concentrated when key element and delete storage
The size key element of storage area where object, the garbage files determination strategy set according to the key element in determination strategy
Can be deleted, when the objective attribute target attribute data of storage object are obtained, will not also obtain storage where storage object
The size data in area.
Strategy modification instruction can also be adjusted for the threshold value of the key element to garbage files determination strategy
When adjusting thresholds are instructed, the threshold value to correspondence key element is updated according to adjusting thresholds instruction, according to renewal
The instruction of the more new strategy of threshold value afterwards, such as adjusting thresholds is indicated " size of file is more than 1G " this strategy
Threshold modifying be 900M, then update after garbage files determination strategy be " size of file is more than 900M ".
Using the garbage files recognition methods of the present embodiment, attribute data original in terminal is taken full advantage of,
And the key element collection comprising at least one key element is provided with according to these attribute datas, and set according to these key elements
Garbage files determination strategies, then on the basis of the current actual attribute data of storage object are obtained, obtain
To the actual value of key element, further according to the threshold value matching feelings of correspondence key element in actual value and garbage files determination strategy
Condition, judges whether storage object is garbage files, and such determination methods have good adaptability, and compared with
Judgment accuracy high.
