.TH mkfs.exfat 8 .SH NAME mkfs.exfat \- create an exFAT filesystem .SH SYNOPSIS .B mkfs.exfat [ .B \-b .I boundary_alignment ] [ .B \-c .I cluster_size ] [ .B \-f ] [ .B \-h ] [ .B \-L .I volume_label ] [ .B \-v ] .I device .br .B mkfs.exfat \-V .SH DESCRIPTION .B mkfs.exfat creates an exFAT filesystem by writing on a special file using the values found in the arguments of the command line. It is invoked automatically by .BR mkfs (8) when it is given the .B \-t exfat option. .PP As an example, to make a filesystem on the first partition on the first SCSI disk, use: .IP .B mkfs.exfat /dev/sda1 .PP .SH OPTIONS .TP .BI \-b " boundary_alignment" Specify the alignment for FAT and start of cluster. Boundary alignment can be specified in m/M for megabytes and k/K for kilobytes. It should be a power of two. Some media like sdcard need this. .TP .BI \-c " cluster_size" Specify the cluster size. Cluster size can be specified in m/M for megabytes and k/K for kilobytes. .TP .BI \-f Performs a full format. This zeros the entire disk device while creating the exFAT filesystem. .TP .BI \-h Prints the help and exit. .TP .BI \-L " volume_label" Specifies the volume label associated with the exFAT filesystem. .TP .BI \-v Prints verbose debugging information while creating the exFAT filesystem. .TP .B \-V Prints the version number and exits. .SH SEE ALSO .BR mkfs (8), .BR mount (8),
