The act of transferring digital data from a device’s internal storage to a Secure Digital (SD) card is a common practice on Android devices. This process involves selecting specific files or folders and relocating them to the designated external storage medium.
Migrating data to an SD card frees up valuable space on the device’s primary storage, improving performance and enabling the user to install more applications or store additional media. This practice was particularly crucial in earlier Android versions and on devices with limited built-in memory, providing a cost-effective method to expand storage capacity.
