Abstract

The invention puts forward an SD (Secure Digital Memory) card reading and writing method and device. The SD card reading and writing method comprises the following steps that: when an SD card to be read and written is judged as a preset SD card, judging whether equipment into which the SD card to be read and written is inserted writes data in a memory into at least one preset SD card or not beforethe SD card to be read and written is accessed into the equipment; if the data is written into at least one preset SD card, taking the at least one preset SD card as a target SD card; judging whetherthe SD card to be read and written is the target SD card or not; and if the SD card to be read and written is the target SD card, storing data written into the SD card to be read and written, and writing data which is not written in the memory of the equipment into a first dictionary in the SD card to be read and written. Through the method, when the SD card which is removed previously is inserted again, the data which is not written into the memory of the equipment can be written into the memory, data reading and writing accuracy is improved, data loss is avoided, and user experience is effectively improved.

Description

technical field [0001] The invention relates to the technical field of software development, in particular to a method and device for reading and writing an SD card. Background technique [0002] When a user uses an electronic device to insert an SD card to be read and written, there is a need to expand the internal storage space of the electronic device. In the related technology, the SD card to be read and written is formatted as an internal storage device, and the media files in the internal storage space of the inserted device are moved to the SD card to be read and written, then the directory inside the inserted device for storing media files is deleted. uninstall. [0003] In this way, the SD card to be read and written is removed from the inserted device, and the directory used to store media files inside the inserted device will not be remounted. At this time, the application that needs to store media files has no place to store files. , making it unusable. Conte...
