The process of transferring data from a device’s internal storage to a Secure Digital (SD) card on the Android operating system enables users to expand storage capacity. This action is generally performed to free up space on the device’s primary storage or to create a backup of files. For example, large media files, such as photos and videos, or downloaded documents can be relocated.
Utilizing an SD card for storage offers several advantages. It allows for increased capacity for applications, media, and other data without requiring an upgrade of the mobile device itself. Historically, this functionality has been crucial for devices with limited internal storage, providing users with a cost-effective solution to manage their data effectively. Moreover, SD cards facilitate easy transfer of data between devices.
