Frequently Asked Questions About SD Card Formatters

Please check the following FAQ to see what you need:

Should I format my SD card as exFAT or FAT32?

When choosing a format option for your SD card, you'll mainly have two choices: exFAT and FAT32. Which one should you pick? The answer depends on a few factors. If compatibility with older devices is a concern, FAT32 is the better choice. However, if you're working with files larger than 4 GB, you'll need to format the SD card as exFAT. Keep in mind that exFAT is a more modern file system, so it's not compatible with as many devices as FAT32 is.

How do I format a micro SD card correctly?

When it comes to formatting a micro SD card, there are a few different methods you can use depending on what type of device the card will be used with. For most smartphones, the best way to format a micro SD card is using the built-in settings menu on the device. This will ensure that the card is formatted with the correct file system and any existing data on the card is deleted. For computers, it's best to use the Partition Master tool to format the micro SD card.

How do I format my 128GB SD card to FAT32?

You can format your 128GB SD card to FAT32 just like any other USB drive or SD card using the Windows formatting tool. However, since FAT32 has a 4 GB file size limit, you'll want to format your SD card to exFAT instead. This format allows for single files up to 16 EB in size, which is more than enough for even the largest video and audio files. To format your 128GB SD card to exFAT, simply insert it into your computer and open the Windows formatting tool. From there, select “exFAT” from the drop-down menu and click “Start.” Your SD card will now be formatted to exFAT and ready for use.
