Opening files from NTFS partition

[robopoulos]

How can files residing on NTFS partition be made accessible from a program (other than Dolphin) on Kubuntu side?

I can see all my win drives from Dolphin and also access any file on any win drive from Dolphin, which I understand would mean that they are mounted. However, while I'm in Qt none of the NTFS folders are available, only drives and folders created by Kubuntu. I need to keep source files on a drive which is accessible from both Windows and Kubuntu.

Thanks
Rob

The KDE file manager (Dolphin) will mount partitions if they are not mounted.

There are many ways to mount partitions automatically:

Ubuntu Community help - Automatically Mount Partitions: https://help.ubuntu.com/community/Au...ountPartitions
Ubuntu Community help - Fstab: https://help.ubuntu.com/community/Fstab


Removable media / KDE:

KDE UserBase Wiki - Removable Devices: https://userbase.kde.org/System_Sett...ovable_Devices

Have a look at System Settings - Removable Devices; IMO a misnomer, as partitions on distinctly unremovable disks appear.

As well, you can use the udisksctl command to do what dolphin does; f.ex.

$ udisksctl mount -b /dev/sda1
Mounted /dev/sda1 at /media/john/boot.

mount through /etc/fstab

one of my ntfs mounts looks like this:
UUID=783AB5E43AB59F94 /mnt/windows7 ntfs defaults,umask=007,gid=46 0 0

Thanks to all so far.

I'm getting half way thru with "sudo udisksctl mount -b /dev/sdb9" I also set auto mounting via System Settings - Removable Devices. Building the source works fine from the ntfs drive but starting the program fails on "Path or permissions wrong?"-error. As the path is now correct (thru media/... ), then are there some priviledges that I must set and how?

Thanks,
Rob

PS. I found the UUID for the drive and edited the fstab but when restarting I get an "unable to mount" - error. I tried to dig info for the other required parameters but that seems a bit complicated.

PPS. Edited just to say that the app works fine if started from my Qt Kubuntu projects folder.

try
make a tmp dir
mkdir stuff
sudo mount /dev/sdb9 stuff/

fstab it if you can mount it manually

udisksctl does not need sudo.

Add a umask option:

udisksctl mount -b /dev/sdf1 -o umask=000

YES! This did the trick, thanks!

PS. Was the reason for the required permissions to run the compiled executable perhaps because I used "sudo udisksctl..." while Qt runs under normal user priviledges?

No, permissions support in Linux for NTFS partitions is a kludge. All the files get the same permissions, I think. Maybe the native NTFS permissions are too different.

All right, thanks a bunch.
