Asked on November 28, 2013
Hi All,
I am using   Files.createDirectories as

FileAttribute<Set<PosixFilePermission>> fileAttributes = PosixFilePermissions.asFileAttribute(perms);

But got below error.

Exception in thread "main" java.lang.UnsupportedOperationException: 'posix:permissions' not supported as initial attribute

Hi Anil,

The error you have mentioned comes when PosixFilePermission is run on windows OS.
Windows does not support PosixFilePermission.
