How do I move file a to a different partition or device in Node.js?

Question

I'm trying to move a file from one partition to another in a Node.js script. When I used fs.renameSync I received Error: EXDEV, Cross-device link. I'd copy it over and delete the original, but I don't see a command to copy files either. How can this be done?

Answer 1

You need to copy and unlink when moving files across different partitions. Try this,

var fs = require('fs'); //var util = require('util');  var is = fs.createReadStream('source_file'); var os = fs.createWriteStream('destination_file');  is.pipe(os); is.on('end',function() {     fs.unlinkSync('source_file'); });  /* node.js 0.6 and earlier you can use util.pump: util.pump(is, os, function() {     fs.unlinkSync('source_file'); }); */ 

Answer 2

I know this is already answered, but I ran across a similar problem and ended up with something along the lines of:

require('child_process').spawn('cp', ['-r', source, destination]) 

What this does is call the command cp ("copy"). Since we're stepping outside of Node.js, this command needs to be supported by your system.

I know it's not the most elegant, but it did what I needed :)
