Constants

 
VDS_FSF_SUPPORT_FORMAT
Value: 0x1
If set, the file system supports format. The drop-down list of a user interface should display only file systems that support formatting.
VDS_FSF_SUPPORT_QUICK_FORMAT
Value: 0x2
If set, the file system supports quick format.
VDS_FSF_SUPPORT_COMPRESS
Value: 0x4
If set, the file system supports file compression.
VDS_FSF_SUPPORT_SPECIFY_LABEL
Value: 0x8
If set, the file system supports file system labels.
VDS_FSF_SUPPORT_MOUNT_POINT
Value: 0x10
If set, the file system supports mounted folders.
VDS_FSF_SUPPORT_REMOVABLE_MEDIA
Value: 0x20
If set, the file system supports removable media.
VDS_FSF_SUPPORT_EXTEND
Value: 0x40
If set, the file system supports extending volumes.
VDS_FSF_ALLOCATION_UNIT_512
Value: 0x10000
If set, the file system supports allocation units of 512 bytes.
VDS_FSF_ALLOCATION_UNIT_1K
Value: 0x20000
If set, the file system supports allocation units of 1 kilobyte.
VDS_FSF_ALLOCATION_UNIT_2K
Value: 0x40000
If set, the file system supports allocation units of 2 kilobytes.
VDS_FSF_ALLOCATION_UNIT_4K
Value: 0x80000
If set, the file system supports allocation units of 4 kilobytes.
VDS_FSF_ALLOCATION_UNIT_8K
Value: 0x100000
If set, the file system supports allocation units of 8 kilobytes.
VDS_FSF_ALLOCATION_UNIT_16K
Value: 0x200000
If set, the file system supports allocation units of 16 kilobytes.
VDS_FSF_ALLOCATION_UNIT_32K
Value: 0x400000
If set, the file system supports allocation units of 32 kilobytes.
VDS_FSF_ALLOCATION_UNIT_64K
Value: 0x800000
If set, the file system supports allocation units of 64 kilobytes.
VDS_FSF_ALLOCATION_UNIT_128K
Value: 0x1000000
If set, the file system supports allocation units of 128 kilobytes.
VDS_FSF_ALLOCATION_UNIT_256K
Value: 0x2000000
If set, the file system supports allocation units of 256 kilobytes.

Remarks

This enumeration provides the values for the ulFlags member of the VDS_FILE_SYSTEM_PROP structure. The SetFileSystemFlags method passes the value as an argument to set the VDS_FPF_COMPRESSED flag.

Note  Additional constants might be added to the VDS_FILE_SYSTEM_FLAG enumeration in future Windows versions. For this reason, your application must be designed to gracefully handle an unrecognized VDS_FILE_SYSTEM_FLAG enumeration constant.
