How to recover data from a mistake overwrite files???

I used a macbook pro with Snow leopard 10.6.1. It was an accident, I copy all files in folder from Ext. HDD to a folder in macbook.

But I've made mistake. A name of folder on Ext. HDD was same as a name of folder on my macbook. While I'm busy, It was an accident. I push enter button to overwrite data.

A 7 GB folder has changed to approx. 2 GB folder.

In this case, Does anyone know how to recover my data. It's an important data, I've done it for a year.

I tried to use data rescue 3.0 and file salvage. But a search result of these 2 programs show me some thing such as 'Pic001 to Pic15555' , 'autocad 001.dwg-autocad 30000.dwg' ,001.pdf-11234.pdf'.
My hardisk is 250 GB but a search result is 300++ GB. I can't find a file that I want to use.

In this case, Is there any program that easy to recover my data???
Pls. suggest, Thanks.

There's really not much you can do. It's been over-written, ie gone 🙁

Sorry but I think the technical term for your situation is knackered.

Perhaps you should look into TIme Machine in the future.

I feel for you… but… there is not much you can do. 🙁

Overwriting is deadly… if you had just deleted it there would have been a chance.

Sorry.
😱

Try something like FileSalvage. The chances are that you have not actually overwritten the files due to the way the FS works.

Of course don't use your machine at all until you do this. Everything you do increases the chances of loosing recoverable data.
