I get files as byte buffers and cannot use fs.stat() method.
So I am try to use buf.length but this length refers to the amount of memory allocated for the buffer object and not actually the content size.
For example I have file with with size 22,449 bytes.
buf.length returns for 39804 for it.
var buff = fs.readFileSync(__dirname + '/test.txt'); console.log( buff.byteLength );
For node 0.10.21 you can try this:
console.log( buff.toString().length );
