File with a .PLE extension contains an encoded text conversation from Windows Live Messenger with the Messenger Plus! Live add-on installed. It is a journal file.
Due to encrypted storing of PLE files – sessions of instant messages cannot be opened and efficiently read with any other way than with the Messenger Plus! Live software, which secures privacy of stored conversations.
