Members| Member name | Value | Description | |
|---|---|---|---|
| FILE_CASE_SENSITIVE_SEARCH | 1 | The specified volume supports case-sensitive file names. | |
| FILE_CASE_PRESERVED_NAMES | 2 | The specified volume supports preserved case of file names when it places a name on disk. | |
| FILE_UNICODE_ON_DISK | 4 | The specified volume supports Unicode in file names as they appear on disk. | |
| FILE_PERSISTENT_ACLS | 8 | The specified volume preserves and enforces access control lists (ACL). For example, the NTFS file system preserves and enforces ACLs, and the FAT file system does not. | |
| FILE_FILE_COMPRESSION | 16 | The specified volume supports file-based compression. | |
| FILE_VOLUME_QUOTAS | 32 | The specified volume supports disk quotas. | |
| FILE_SUPPORTS_SPARSE_FILES | 64 | The specified volume supports sparse files. | |
| FILE_SUPPORTS_REPARSE_POINTS | 128 | The specified volume supports reparse points. | |
| FILE_SUPPORTS_REMOTE_STORAGE | 256 | The file system supports remote storage. | |
| FILE_RETURNS_CLEANUP_RESULT_INFO | 512 | On a successful cleanup operation, the file system returns information that describes additional actions taken during cleanup, such as deleting the file. File system filters can examine this information in their post-cleanup callback. | |
| FILE_SUPPORTS_POSIX_UNLINK_RENAME | 1024 | The file system supports POSIX-style delete and rename operations. | |
| FILE_VOLUME_IS_COMPRESSED | 32768 | The specified volume is a compressed volume, for example, a DoubleSpace volume. | |
| FILE_SUPPORTS_OBJECT_IDS | 65536 | The specified volume supports object identifiers. | |

| FILE_SUPPORTS_HARD_LINKS | 4194304 | The specified volume supports hard links. | |
| FILE_SUPPORTS_EXTENDED_ATTRIBUTES | 8388608 | The specified volume supports extended attributes. An extended attribute is a piece of application-specific metadata that an application can associate with a file and is not part of the file's data. | |

| FILE_SUPPORTS_SPARSE_VDL | 268435456 | The file system tracks whether each cluster of a file contains valid data (either from explicit file writes or automatic zeros) or invalid data (has not yet been written to or zeroed). | |
