Embodiment
Describe the present invention in detail below with reference to accompanying drawing and in conjunction with the embodiments.It should be noted that do not conflicting
In the case of, the feature in embodiment and embodiment in the application can be mutually combined.
The invention provides fragmented file in a kind of data recovery to collect matching process, so as to avoid current file from recovering soft
For part after file index is destroyed, fragmented file recovers the ineffective present situation of integrality.
Fig. 1 show the file management schematic diagram of the embodiment of the present invention 1, comprises the following steps：
Step 101：Retrieving：According to keyword match scheme, the file header in retrieval fragmented file region；
Step 102：Resolving：The information that the file header obtained according to retrieving includes, analysis this document location
The address section in domain；
Step 103：Position fixing process：Based on different content feature, file storage delimited, determines that the target of this document is deposited
Storage area field parameter；
Step 104：Collection process：The target storage field parameter obtained according to position fixing process, data storage before and after retrieval
The content in region, realize the collection of fragmented file.
This method can greatly reduce the mistake that the raw data collection stage of fragmented file recovery is likely to occur, and make scattered
File collection matching becomes efficient, accurate.
It is as follows to implement step：
1) file header of the file to be searched for is retrieved, due to the especially specific form of file header, keyword can be passed through
The method matched somebody with somebody, is retrieved in storage region, identifies whether the data block includes key message；
2) information included according to the file header being retrieved, the address section of analysis this document region.Generally come
Say, the binary sequence of file header can include many attribute informations related to this document., can by analyzing these attribute informations
To know the file type of this document, the form of end-of-file has also been known that, has then positioned end-of-file, estimation obtains this document
Size.If more than one file is contained in the region, set of variables (Ai) is set to carry out warehouse to the key message of different files
Storage；
3) the different content feature based on different file types, the scope that this document may store delimited, locks this document
" target storage domain " (TargetArea) parameter.Information in comprehensive analysis file and end-of-file, different files can be obtained
Size.If file i size is Ai.TargetArea, all Ai.TargetArea sum is stored by accumulator S, also
The area size is determined；
4) according to target storage field parameter, retrieval storage region is the data content in S space, with reference in file header
Correlation attribute information, realize the collection of fragmented file.File i fragment content is stored in Ai different attribute item, classification
It is collected.
In summary, the present invention can greatly reduce the mistake that the raw data collection stage of fragmented file recovery is likely to occur
By mistake, fragmented file is collected matching becomes efficient, accurate.
Fig. 2 show the file management method process chart of the embodiment of the present invention 2, comprises the following steps：
Step 201：Obtain and carry target keywords and the File header information of file and according to described in the storage region
File header information, obtain file type；
Further, the file attribute in the File header information, file type is obtained.
Step 202：According to content characteristic corresponding to the file type, it is determined that target storage corresponding with the file
Field parameter；
Step 203：According to the file size of acquisition, the hunting zone value of storage region is determined；
Further, according to the file type, end-of-file information is determined；
According to the File header information, the end-of-file information, file size is obtained.
Especially, step 202, the no strict time sequencing of execution of step 203, can successively perform (can first hold
Row step 202, then step 203) is performed, it can also perform simultaneously.
Further, the file is one or more.
Preferably, if the file is multiple, the search model by accumulator to storage region corresponding to each file
Enclose value to be added up, it is determined that the hunting zone value of final storage region.
Step 204：According to the target storage field parameter, the text in the space that storage region is hunting zone value is obtained
Part.
