I am using Ubuntu 12.04. When I open a pdf file in Evince, and want to click "Save as" in the menu of Evince to create a new directory on a ntfs partition (shared between Ubuntu 12.04 and Windows 7 installed on the same hard drive but different partitions) and save the file there, sometimes I am able to create a new directory, and sometimes I am not because it says
The folder could not be created
"Error creating directory: Permission denied"
But I can always create a new directory under EXT4 partition created when installing Ubuntu.
I was wondering how I can create a new folder on that shared ntfs partition, when going through Evince?
