Problems solved by technology

[0002] In the prior art, when using a mobile terminal, the files or data stored in the mobile terminal may be accidentally deleted due to the negligence of the user. For example, when the existing mobile phone or tablet computer (pad) deletes relevant files or data, Users cannot restore these related files and data with a very simple operation, and once the mobile phone or tablet computer (pad) deletes files or data (such as text messages, address books, materials, and data content in applications or files) Finally, when you want to restore the deleted files, you can only restore the deleted files through special software, and the operation of the related recovery software is more complicated, inconvenient to use, and the execution efficiency is low

Embodiment 1

[0061] Step a1: The mobile terminal obtains a delete operation, which indicates to delete the file A stored in the mobile terminal;

[0062]Step a2: The mobile terminal deletes file A, and releases the storage space occupied by file A;

[0063] The deletion operation of the mobile terminal at this time only changes the state of the storage area occupied by the data corresponding to file A, and releases the hard disk storage resources occupied by file A. The delete operation changes the state of the storage area occupied by the corresponding data of file A to writable. Only after the data stored in the mobile terminal covers the storage area occupied by the file A, the file A is completely deleted and cannot be recovered. Therefore, this embodiment can take advantage of this feature to restore file A before other data overwrites the storage area occupied by file A;

[0064] Step a3: when the mobile terminal is overturned and / or shaken, the mobile terminal generates a recovery...

Embodiment 2

[0069] Step b1: the mobile terminal obtains a delete operation, the delete operation indicates to delete the file A stored in the mobile terminal;

[0070] Step b2: The mobile terminal deletes file A, and releases the storage space occupied by file A;

[0071] The deletion operation of the mobile terminal at this time only changes the state of the storage area occupied by the data corresponding to file A, and releases the hard disk storage resources occupied by file A. The delete operation changes the state of the storage area occupied by the corresponding data of file A to writable. Only after the data stored in the mobile terminal covers the storage area occupied by the file A, the file A is completely deleted and cannot be recovered. Therefore, this embodiment can take advantage of this feature to restore file A before other data overwrites the storage area occupied by file A;

[0072] Step b3: within a preset time after file A is deleted, when the mobile terminal turns o...

Embodiment 3

[0077] Step c1: the mobile terminal obtains a delete operation, the delete operation indicates to delete the file A stored in the mobile terminal;

[0078] Step c2: The mobile terminal deletes the image identification corresponding to the file A;

[0079] The deletion operation of the mobile terminal at this time is only to delete the image identification corresponding to file A on the user interface. The mobile terminal user can perform various operations on file A through the image identification. After deleting the image identification, the mobile terminal user will not be able to perform Any operation on file A;

[0080] Step c3: within a preset time after deleting the image mark of file A, when the mobile terminal turns over and / or shakes, the mobile terminal generates a recovery command through the obtained parameter value collected by the sensor, instructing to restore the deleted file A;

[0081] Specifically, the sensor in the mobile terminal is a gravity sensor. Th...

Abstract

The invention provides a method of recovering mistakenly-deleted files and a mobile terminal, and belongs to the field of mobile communication. The method of recovering the mistakenly-deleted files can be applied in the terminal. The terminal comprises a sensor. Parameters collected by the sensor are used for judging space position changes of the mobile terminal. The method includes obtaining a deleting operation, responding to the deleting operation, deleting first data corresponding to the deleting operation, obtaining the parameters collected by the sensor, judging whether the parameters meet preset conditions and generating a judgment result. When the judgment result shows that the parameters meet the preset conditions, a recovery command is generated. The first data deleted by the deleting operation are recovered according to the recovery command. By means of the technical scheme, the mistakenly-deleted files in the mobile terminal can be conveniently and fast recovered.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for recovering mistakenly deleted files and a mobile terminal. Background technique [0002] In the prior art, when using a mobile terminal, the files or data stored in the mobile terminal may be accidentally deleted due to the negligence of the user. For example, when the existing mobile phone or tablet computer (pad) deletes relevant files or data, Users cannot restore these related files and data with a very simple operation, and once the mobile phone or tablet computer (pad) deletes files or data (such as text messages, address books, materials, and data content in applications or files) Finally, when you want to restore the deleted files, you can only restore the deleted files through special software, and the operation of the related recovery software is more complicated, inconvenient to use, and low in execution efficiency. Users of mobile phones (general user...
