How do I programmatically change file permissions?

Full control over file attributes is available in Java 7, as part of the “new” New IO facility (NIO.2). For example, POSIX permissions can be set on an existing file with setPosixFilePermissions(), or atomically at file creation with methods like createFile() or newByteChannel().

What is the best place for storing uploaded images, SQL database or disk file system? [closed]
