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.

What to do before cloning SD card?

No matter why you clone your SD card, the following work is necessary for a smooth process and satisfactory result.

Prepare an SD card reader

To connect the SD cards to your computer and start clone, you need to prepare an SD card reader: plug your SD card into it and connect this reader to your PC.

Back up anything important on the cloned SD card 

Since the cloning process will be erased during the cloning process, please ensure you have moved everything vital to another safe location. For this task, the free backup software - AOMEI Backupper Standard is recommended.

Check the both SD cards' storage space

Make sure the SD card you are cloning to has enough space to hold all contents in the source SD card. If there is not enough space, you had better remove some files or programs that are unnecessary from the SD card to make it smaller to fit into the destination SD card.
