Windows Live Writer is an awesome tool for professional bloggers and strongly recommended desktop authoring tool. We earlier covered a backup tool for WLW but that is not much reliable. There may be a scenario where you want to send the Windows Live Writer post which you have written in proper format for any other blog to the admin of that site then you can send the Post File (.wpost) to him. Or if you are moving to some other place and want to carry the post file with you so that you can use any other system to post publish that file then you can use this tip to do the same.
