Can those Password-protected folders be copied away by others?

No. The "folder" left after password protection is just a shortcut about 1 KB in size. In fact, your folder is still protected and saved in the original disk partition. Even if this 1 KB file is copied away by others, your protected folder is still safely kept. Therefore, a password-protected folder cannot be moved.

If you want to back up a password-protected folder, please unprotect it first and then back up, otherwise what you back up is only a shortcut.
