Provides information about file systems that are supported for formatting volumes.
Syntax
typedef struct _VDS_FILE_SYSTEM_FORMAT_SUPPORT_PROP {
ULONG ulFlags;
USHORT usRevision;
ULONG ulDefaultUnitAllocationSize;
ULONG rgulAllowedUnitAllocationSizes;
WCHAR wszName;
} VDS_FILE_SYSTEM_FORMAT_SUPPORT_PROP, *PVDS_FILE_SYSTEM_FORMAT_SUPPORT_PROP;
Members
- ulFlags
-
Bitwise-OR of any of the values defined in the VDS_FILE_SYSTEM_FORMAT_SUPPORT_FLAG enumeration.
- usRevision
-
The revision of the file system, if any. This member is expressed as a 16-bit binary-coded decimal number, where a decimal point is implied between the second and third digits. For example, a value of 0x0250 indicates revision 2.50.
- ulDefaultUnitAllocationSize
-
Default allocation unit size, in bytes, that will be used by the file system for formatting the volume. This value must be a power of 2 and must also appear in the rgulAllowedUnitAllocationSizes member.
- rgulAllowedUnitAllocationSizes
-
A zero-terminated array of allocation unit sizes, in bytes, that are supported by the file system for formatting the volume. The case where the array will not be zero-terminated is if there are MAX_FS_ALLOWED_CLUSTER_SIZES_SIZE number of elements in the array. Each of the values in the array must be a power of 2.
- wszName
-
Null-terminated Unicode string indicating the name of the file system. Possible values include the following.
Value Meaning - L"CDFS"
CD-ROM file system (CDFS)
- L"FAT"
FAT file system
- L"FAT32"
FAT32 file system
- L"NTFS"
NTFS file system
- L"UDF"
Universal Disk Format (UDF) file system
Remarks
If an OEM partition is formatted as FAT or FAT32, the partition type does not change. If it is formatted with NTFS, the partition type changes to PARTITION_IFS (0x07). For information about partition types, see CREATE_PARTITION_PARAMETERS.
