node.js fs.rename() error enoent

Question

after uploaded a file to my server i try to move it to another folder(same disk), and i got thie error

{[Error:ENOENT,rename 'F\myproject\1b231234nsdifhoi2323']
  errno:34,
  code:ENOENT,
  path:'F\\myproject\\1b231234nsdifhoi2323'
}

am on windows and use

app.use(express.bodyParser({
    uploadDir:'./Temp'
}));

here is my rename code

exports.upload = function(req, res,next){
    console.log( req.body);
    console.log(req.files);
    var tmp_path = req.files.product_video.path;
    var target_path = '\\Video\\' + req.files.product_video.name;

    console.log(tmp_path);       // Temp\1b231234nsdifhoi2323
    console.log(target_path);    // \Video\name

    fs.rename(tmp_path, target_path, function(err) {
        if (err) {
            console.log(err)
        };
        fs.unlink(tmp_path, function() {
            if (err){
                console.log(err)
            }else{
                res.send('File uploaded to: ' + target_path + ' - ' + req.files.product_video.size + ' bytes');

            }
        });
    });
};

it looks like i get the path wrong,but i cannot figure it out !

Solution

You are accessing an unexisting file - because a path does not.

Try edit path:
change "F\myproject\1b2" to "F:/myproject/1b2" or "F:\myproject\1b2"

If doesn't work, use: (__dirname will make a path relative to the script)
__dirname + "/../../myproject\1b2"

For debugging:
Try read this file (if you get same error - it means that path is bad and rename is fine)
