Problems solved by technology

[0004] Generally speaking, digital cameras are powered by batteries. If the power supply cannot be supplied during the process of writing files to the memory card, incomplete files will be stored in the memory card.
However, due to the fact that part of the file configuration table information has been written, the available space in the memory card is reduced.

Abstract

The invention relates to a method for storing data and an electronic device using the same. When the electronic device is to store the data into a memory card, the data is only written into the memory card. Moreover, file information and information of a corresponding position in the memory card, at which the data is stored, are stored into a buffer block of the electronic device. After the action of closing a file is executed, the file information and the position information which are recorded into the buffer block are written into the memory card.

Description

technical field [0001] The invention relates to a data access mechanism, in particular to a data storage method and an electronic device. Background technique [0002] With the advancement of digital technology, traditional cameras that use film to record images have been gradually replaced by digital cameras that use digital media such as memory cards to record images. Today, the volume of digital cameras is getting smaller and smaller, so that users can carry them with them. On the other hand, the capacity of memory cards used in digital cameras is getting bigger and bigger, and can record more images, which is enough for users to fully record events that occur every moment in various shooting situations. [0003] Generally, when the memory is formatted, it is divided into a main boot block, a file allocation table (File Allocation Table, FAT) block, a directory table block and a data block. Wherein, the file configuration table block is used to store space information o...
