Does it use low level system functions?
No. G2 shredding does not use low-level file system functions. Other wipe programs may write over areas of the disk without having locked the space. This will lead to problems when Windows or other programs create new files at the same time. That information is lost. The file system may be damaged or Windows may not start any more. This cannot happen with G2 shredding because we don’t use low-level file system functions. This also means that G2 shredding is independent of the file system, and works with FAT, FAT32, NTFS-4, NTFS-5, and even newer extensions to be introduced with Windows 7.
