Understanding the Format Command
The format command is a built-in Windows command that allows you to format storage devices such as memory cards, USB drives, and hard drives. The command has a number of options that allow you to specify how the device should be formatted.
The most important option is the `/FS` option, which specifies the file system that you want to use to format the device. The most common file systems are NTFS, FAT32, and exFAT.
NTFS is the default file system for Windows and is the most versatile. It can be used with both internal and external storage devices and supports large file sizes.
FAT32 is an older file system that is compatible with a wider range of devices than NTFS. However, it has some limitations, such as a 4GB file size limit.
exFAT is a newer file system that is designed for flash memory devices. It has no file size limit and is compatible with both Windows and macOS.

Frequently Asked Questions
Q: Why should I format my memory card by CMD instead of using the built-in formatting tool in Windows?
A: Formatting a memory card by CMD offers several advantages over using the built-in formatting tool in Windows. First, CMD allows you to specify the file system that you want to use to format the card, giving you more control over the formatting process. Second, CMD can be used to format cards that are not recognized by the built-in formatting tool.
Q: What is the difference between a quick format and a full format?
A: A quick format erases the file system from the memory card but does not perform a full scan of the card for errors. A full format erases the file system and performs a full scan of the card for errors, which can take longer but is more thorough.
Q: Can I format a memory card that is write-protected?
A: No, you cannot format a memory card that is write-protected. You will need to remove the write protection from the card before you can format it.
