But code which I referred check both number of fat tables and number of allocation bitmaps (as they are represented by one member in boot sector structure). > Btw, only Windows CE supported this. Is this information based on some real tests? Or just from marketing or Microsoft's information? (I would really like to know definite answer in this area). Because Microsoft says one thing in their FAT32 specification, second thing described in their FAT implementation and thing thing is how it is really implemented (in fatfast.sys kernel driver which is open source). So I would be really careful about how MS's exfat.sys implementation is working. -- Pali Rohár pali.rohar@xxxxxxxxx
