My hard disk is divided into 3 partitions :

1. C:/ windows 7 partition
2. D:/ shared data partition
3. Ubuntu partition ( invisible in windows )

I have created some screenshots in Ubuntu and stored them in "Screenshots" folder in D:/ .

Now, I want to delete "Screenshots" folder using Windows but I can't.

I tried to delete it using cmd ( run as administrator ) and I got errors

Is that related to system files concept ( ext4 versus ntfs ) ?
