Note that Linux and mkfs.vfat do not care about the partition type id. Also mkfs.vfat is the same as mkfs.msdos and mkdosfs. By default, when not forcing the FAT type with -F, it will select the type depending on the volume size. Of course it will select FAT32 for a 50 GB partition.

The documents I found seem to tell only part of the story then. OK, I found this: https://en.wikipedia.org/wiki/File_Allocation_Table "Further, the term "VFAT" has led to various misconceptions as well,[nb 1] as it is sometimes erroneously used as if it would describe another variant of FAT file system to be distinguished from the FAT12, FAT16 and FAT32 file systems, while in reality it does not specify another file system, but an optional extension, which can work on top of any FAT file system, FAT12, FAT16 or FAT32. Volumes utilizing VFAT long-filenames can be read also by operating systems not supporting the VFAT extension, as long any operating systems that support the underlying file system (FAT12, FAT16, or FAT32)." Conclusion: Long Wind's partition has type b, that is FAT32. Now making a filesystem with mkfs.vfat /dev/sda7 should make it readable and writable for WinXP.

It is only a way to use long filenames with any FAT type, FAT12, FAT16 or FAT32. So vfat on FAT32 has the limits of FAT32.

Install dosfstools and use the mkfs.vfat command. BTW, Windows XP is unsupported and thus a security risk, as bugs are not patched by MS anymore. -- Everyone's in a high place when you're on your knees. Eduardo M KALINOWSKI edua...@kalinowski.com.br

VFAT allows long filenames - otherwise it is not better than FAT16. That means it allows only partitions up to 2GB. FAT32: Partition max size for FAT32: 2TB allows only files < 4GB https://www.partitionwizard.com/convertpartition/fat32-partition-size-limit.html All the best to you Eike
need help on vfat partition
i create a vfat partition at sda7 using fdisk of linux partition id is set to b then i go to XP and format it but fail maybe the reason is the partition is too big it's more than 50G What should I do? Thanks! PS: the choice of vfat is that IMO vfat is more cross-platform
