16 config NTFS3_64BIT_CLUSTER
17 bool "64 bits per NTFS clusters"
18 depends on NTFS3_FS && 64BIT
20 Windows implementation of ntfs.sys uses 32 bits per clusters.
21 If activated 64 bits per clusters you will be able to use 4k cluster
22 for 16T+ volumes. Windows will not be able to mount such volumes.
24 It is recommended to say N here.
26 config NTFS3_LZX_XPRESS
27 bool "activate support of external compressions lzx/xpress"
30 In Windows 10 one can use command "compact" to compress any files.
31 4 possible variants of compression are: xpress4k, xpress8k, xpress16k and lzx.
32 If activated you will be able to read such files correctly.
34 It is recommended to say Y here.
36 config NTFS3_FS_POSIX_ACL
37 bool "NTFS POSIX Access Control Lists"
41 POSIX Access Control Lists (ACLs) support additional access rights
42 for users and groups beyond the standard owner/group/world scheme,
43 and this option selects support for ACLs specifically for ntfs
45 NOTE: this is linux only feature. Windows will ignore these ACLs.
47 If you don't know what Access Control Lists are, say N.
