Frequently Asked Questions

Find Quick Answers

Does this tool actually format my physical SD card?

No, this is a simulation tool that processes SD card image files. It doesn't physically format hardware SD cards but shows you exactly what would happen during an NTFS format operation.

What are the advantages of NTFS over FAT32 for SD cards?

NTFS supports larger file sizes (over 4GB), better reliability with journaling, improved security with file permissions, and better performance with large files. However, some older devices may not support NTFS-formatted cards.

What file types can I upload?

You can upload SD card image files (.img, .iso) or any file to simulate the formatting process. The tool will analyze the file and provide NTFS formatting details.

Is there a file size limit?

There's no artificial limit, but very large files may take longer to process depending on your browser and device capabilities.
