Not permitted to create a new directory on a ntfs partition?

Question

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?

Edit your fstab file and add add the gid=1000 to allow all the users in your group to have rights on the partition or else you can use the uid=1000 so only your user has privileges on it. The fstab file is located at /etc/fstab and you can edit such options with the gnome-disks-manager app. Reboot or issue the mount -a command as root to apply changes to fstab.
