Problems solved by technology

Therefore, after the data flag is set as deleted, it can no longer be displayed on the above-mentioned electronic device, and the user cannot see the data.
However, due to misoperation, after the user mistakenly deletes important data on the electronic device using the FLASH storage device, although the mistakenly deleted data still exists in the electronic device, the user cannot find and use it, which brings unnecessary troubles to the user. Trouble, reduce the user-friendliness of this electronic device

Embodiment Construction

[0040] In order to make the above objectives, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] At present, many electronic devices use FLASH storage devices to store data, such as mobile phones, handheld computers, MP3, MP4, etc. Due to the storage characteristics of the FLASH storage device, the above electronic equipment only changes the flag bit of the selected data from valid to deleted when deleting data. When the electronic device searches and displays data, it only searches and displays the data whose flag bit is valid. After the flag bit of the data is set to be deleted, it can no longer be displayed on the electronic device. After the electronic device deletes important data by mistake, the user can retrieve the deleted data from the FLASH storage device, select the data to be restored, save the sel...

Description

Technical field [0001] The present invention relates to the field of electronic equipment, in particular to a recovery method and recovery system after data is accidentally deleted, and electronic equipment. Background technique [0002] With the development of science and technology, the functions of various electronic devices are constantly being introduced to meet the needs of people's daily life. Especially small electronic devices, which are convenient to carry, simple to operate, and can store a large amount of data, have become necessities for people's lives and work. People are accustomed to storing some important data information in small electronic devices for easy search and use. For example, mobile phones are often used to store data information such as phonebooks, short messages, and multimedia messages. When the data information stored in the electronic device exceeds a certain amount, the user often deletes some relatively unimportant data information in order to s...
