• Where - on client side, or on server side? What is your end goal with this? – Pekka Commented Apr 24, 2011 at 13:07

• @delnan hi friend. i'm not finding these for any malicious purpose. So if you predict something like that, you are wrong.Thanks for your ment. – thecodeparadox Commented Apr 24, 2011 at 13:34

• 1 I'm not saying you have malicious intents. But browser JS runs in a sandbox for a reason - incredible potential for malware otherwise (heck, even with the sandbox people find ways to abuse it!). – user395760 Commented Apr 24, 2011 at 13:36

There are 2 HTML5 APIs of interest.

The File API which allows you to read files (of a users choice). Most modern browsers implement this.

The File Write API which allows you to write to files. No browsers implement this as of now.

I presume you can also use IE only ActiveX controls to do file manipulation on windows.

In any end (client/server)

You weren't specific about which server side JS implementation you are using, so for Node.js:

See the file system section of the Node.js documentation

As I can understand from your question you are trying to do file operation at client end. If you are using IE and windows operating system, you can do that using FileSystemObject. This doesn't work for other browser and other operating systems as FileSystemObject is ActivexObject given by Windows.
