and I found Using Node.js I get, "Error: EISDIR, read" and Node.js Error: EISDIR, open Error similar error message, my UploadTemporary folder already exists do I mess something wrong? I don't get it, if its not a directory what else can be?

var multipart = require('connect-multiparty');
var fs = require('fs');
var path = require('path');
var appDir = path.dirname(require.main.filename);

...
var sourceFile = req.files.file[0].path;
var destinationFile = appDir + '/assets/images/UploadTemporary/';

var source = fs.createReadStream(sourceFile);
var destination = fs.createWriteStream(destinationFile);

source.pipe(destination);
source.on('end', function () {
  fs.unlinkSync(sourceFile);
});

You need to give the actual filename in the `destinationFile` — thefourtheye, Aug 11 '15 at 07:13
you mean something like this `var destinationFile = appDir+'/assets/images/UploadTemporary/'+newfilename` — user1775888, Aug 11 '15 at 07:14
Exactly. I think you are thinking that giving just the directory name will create a file with the source file name, right? — thefourtheye, Aug 11 '15 at 07:15

When you are writing a file to a specific directory, you need to give the actual destination file name as well. Unlike cp command, the destination filename will not be inferred by fs module.

In your case, you are trying to write to a directory, instead of a file. That is why you are getting EISDIR error. To fix this, as you mentioned in the comments,

var destinationFile = appDir + '/assets/images/UploadTemporary/' + newfilename;

include the file name as well.
