Necessary to copy SD card to SD card Windows

As is well known, SD cards have become a vital part of our new-age technology. These small and tiny storage chips are widely used in portable devices like mobile phone, digital camera or game gadgets to store data. Sometimes, we might need to copy SD card to another SD card for the following reasons:

1. To upgrade SD card to a larger SD card

If your current SD card is almost full and leaves little space for any new data, you may want to copy SD card to another larger card for an upgrade.

2. To back up data on SD card

If you have saved many important files on the SD card and you wanted to make a backup to avoid significant data loss when your SD card is damaged, copying SD card to another SD card could be a nice option.

3. To transfer files from SD card to another SD card fast

Compared with copying and pasting all files from one SD card to another card one by one, cloning the entire card will be a quicker, more convenient and time-saving way to transfer files between two SD cards.
