UnsupportedOperationException when copying files from SMB on Windows #39

Closed qwertzguy closed 9 years ago

qwertzguy commented 9 years ago

When doing this:

Path source = Paths.get("\\\\filer.domain.local\\folder");
Path target = Paths.get("c:\\tmp");
MoreFiles.copyRecursive(source, target);

I get this exception:

I suspect this actually happens for any paths on Windows and is not specific to SMB paths - copyRecursive should work even if getPosixFilePermissions is not not supported.
