The embodiments of the invention provide a kind of method of media file backup, performed by user equipment, specifically set by user The media file back-up device of standby middle setting performs, and the user equipment includes the first storage device and the second storage device, The embodiment of the present invention is that what type of storage device does not limit to the first storage device and the second storage device, citing and Speech, the first storage device and the second storage device may each be any one following storage device：Hard disk, floppy disk, USB flash disk, CD, Mobile hard disk, disk, storage card, as shown in figure 1, the method for media file provided in an embodiment of the present invention backup includes following step Suddenly：
S11, the media file stored in the first storage device is scanned, to determine it is important whether the media file is marked with File identification.
Firstly the need of explanation, in this step, the media file that is scanned is stores at least in the first storage device One media file.
For example, in this step, the media file can include audio media files, video media file and picture At least one of file.Wherein, audio media files refer to store sound-content file, such as form be MP3, CD, WAVE (* .WAV), WMA, RealAudio etc. file；Video media file then refers to the text for storing various dynamic image contents Part, such as the file that form is WMV, AVI, MP4, RM/RMVB, kmv etc.；And picture file refers to store in various tangible things The file of appearance, such as the file that form is JPEG, TIFF, BMP, GIF, PNG etc..
Obviously, the media file can also be other kinds of media file, and the present invention is not limited this.
It is understood that the media file stored in the first storage device include it is extremely important for a user , user want the media file that preserves for a long time, in order to ensure the security of this part of media file, the embodiment of the present invention provides Backup method in, before this step is S11 steps, user will be these important media file marking value documents marks. For example, user equipment can provide vital document option for media file, user can by choose the option so as to for The media file marking value documents identify；For another example it is important that user equipment, which can receive user to mark certain media file, The instruction of file, after the instruction is received, user equipment adds vital document mark in the attribute information of the media file, As the media file marked vital document mark.So, in this step, user equipment can find this by scanning A little important media files, and then the media file important to these backs up, and the safety of these media files is effectively ensured Property.
Specifically, this step can have three kinds of specific implementations, it is as follows respectively：
First, in one embodiment of the invention, user equipment can receive the scan instruction of user, and described In the case that scan instruction instruction is scanned to the media file stored in first storage device, according to the scanning of user Instruction, the media file stored in first storage device is scanned, to determine whether the media file is marked with important text Part identifies；That is, this step can be carried out according to the wish of user, user being actually needed according to oneself, with When issue scan instruction.For example, user equipment can provide the user the function choosing-item of scanning medium file, be selected in user When selecting the function choosing-item, that is, start to perform this step.
Second, user equipment can scan the media stored in the first storage device according to the scan period pre-set File, to determine whether the media file is marked with vital document mark.The length of the scan period pre-set is unlimited, Can arbitrarily it set, such as 1 day, 1 week, 2 weeks, one month etc., the scan period can be that user pre-sets or used The default setting of family equipment.
Third, user equipment can monitor user in real time to the operation of the media file stored in the first storage device, one Denier monitors to determine the media that the media file that user stores the first storage device is operated, and scanning user was operated File, to determine whether the media file that user operated is marked with vital document mark.Here the user equipment sayed is supervised " operation " surveyed, can paste new media file including user into the first storage device, and user opens the first storage device Closed after the media file of middle script storage, or, user changes the content of the media file stored originally in the first storage device, Or, user changes attribute of media file stored originally in the first storage device etc., the present invention is not limited this.Citing For, once user equipment detects that user has pasted new media file into the first storage device, will start to scan this new Media file, with determine the media file whether be marked with vital document mark.
It is understood that in one embodiment of the invention, during user equipment can be in a manner of compatible above-mentioned three kinds At least two modes are scanned.
It should be noted that the present invention is not limited the specific implementation of this step, can be three of the above mode At least one of, can also be other scan modes.
In this step, if user equipment scans are marked with vital document mark to media file, step S12 is performed, and For the media file of unmarked vital document mark, user equipment can be without any processing.
S12, if the media file is marked with vital document mark, obtain the directory information of the media file.
It should be noted that in the embodiment of the present invention, directory information refers to the path that media file is deposited in storage device Information.For example, the directory information of certain media file is " E:Beijing Company research and development department 1 communication set work courseware .wma ".
Specifically, user equipment can read the attribute information for the media file for being marked with vital document mark, to obtain The directory information of this document, certainly, user equipment can also have other modes for obtaining directory information, and the embodiment of the present invention is to this Do not limit, for details, reference can be made to prior art, repeat no more here.
S13, according to the media file directory information of the acquisition, the media file is backuped into the second storage device On.
Special backup memory block can be provided with second storage device, in this step, user equipment will can be marked with The media file of vital document mark is backuped in the backup memory block in the second storage device.
The method of the media file backup of the embodiment of the present invention, scans the media file stored in the first storage device, When the media file is marked with vital document mark, according to the directory information of this document, the media file is backuped to second In storage device, that is to say, that it can remember that the media file for having important media file identification is backed up with automatic benchmarking, such one Come, it is only necessary to which important media file is marked user, and the operation such as duplication manually is carried out to complete to back up, therefore without user It is effectively simplified the troublesome operation that user is backed up, additionally it is possible to preferably avoid causing due to forgetting or the omission of user File lose, the security of backup is effectively ensured, so as to significantly improve Consumer's Experience, and any chip need not be increased, had Effect reduces cost.
It is understood that in the embodiment of the present invention, before S11 steps, user needs the important text thought to it Part marking value documents are identified, that is to say, that user equipment is needed under the instruction of user, is media text according to the requirement of user Part marking value documents identify, and are below that media file marks important media file identification to be described in detail to user equipment.
Specifically, in the backup method of media file provided in an embodiment of the present invention, user equipment is to media file mark Remembering the method for important media file identification includes following two kinds, but is not limited to following two kinds：
One：
When user needs to close media file, user would generally click on the X button of the media file, that is, issue pass Instruction is closed, at this moment, user equipment can be sent important when receiving out code of the user to media file to the user File mark is prompted, for example, ejecting a dialog box, is shown in dialog box：Whether it is this document marking value documents mark, and gives Go out the option button of "Yes" and "No", the media file marking value documents mark for its closing is prompted the user whether with inquiry Know.If the user feels that this Documents Comparison is important, prompting will be marked to send marking value documents mark according to vital document and referred to Order, for example, clicking on the "Yes" button in dialog box, instruction user equipment identifies for the media file marking value documents, user After equipment receives the instruction, identified for the media file marking value documents that user closes, certainly, if the user feels that this File is inessential, without mark, according to vital document prompting can be marked to send without mark instructions, for example, clicking on dialog box In "No" button, instruction user equipment do not have to for the media file marking value documents identify.
It is understood that this mode is not limited to user when closing media file, can also be realized on other opportunitys, For example, when user preserves media file, for example, user is after the operation such as modified to a media file, it will usually click on Save button or drop-down menu " save options ", that is, issue preservation instruction, and user equipment can receive user to media During the preservation instruction of file, ejection vital document mark prompting, issued so as to mark prompting according to vital document in user Under instruction, operation is marked or without marking operation, repeats no more here.
It should be noted that for example, user equipment can be ejection to user's transmission vital document mark prompting The form of dialog box, to ask the user whether to mark, user if it is desired to mark then selection is, it is on the contrary then select no.Certainly, user The prompting mode of equipment is not limited to this mode, can also be other modes.
Secondly：
When user runs into it and is considered important media file every time, it can use and edlin is entered to the media file Mode, identified for the media file marking value documents.Specifically, user will be issued for the media file to user equipment Edit instruction, in the embodiment of the present invention, the edit instruction can refer to any operation that user wants editing media file, example Such as, user clicks on the operation of right mouse button at the icon of media file, and user clicks on the toolbar or menu bar of media file In any button operation etc., when user equipment detects this operation of user, will display for a user and user operate Corresponding media file editing options, for example, ejection drop-down menu, the drop-down menu include at least one editing options, Include the option of marking value documents mark in shown at least one editing options, user passes through the important text of selected marker The option of part mark marks the media file, i.e. user equipment receives the option that user identifies to the marking value documents Selection instruction, so as to according to the instruction be user edit media file marking value documents mark.
For example, the edit instruction of user can first click on left button for user and choose certain media file, then click right button, At this moment, user equipment would indicate that editing options menu, and including " vital document mark " option, and then user chooses the choosing The media file is marked item.
