Accesing XP files permissions

[Angel Massa]

I have XP and Vista installed each one of different drives on my PC.

Yesterday I booted with Vista and tryied to open my pictures stored in my XP
drive on Mi Pictures folder of my user account. Vista warned that I need
permissions and after accepting the warning I have no option to enter my
login to access the files.

Also my user name and password on Vista is the same that on XP so I will had
to have access to the files without problems, right?

Why I can access my files if I'm identified witht the same user on Vista and
the other drive is a NTFS system?

Regards,
Angel.

Hi Angel,

Yesterday I booted with Vista and tryied to open my pictures stored in my
XP drive on Mi Pictures folder of my user account. Vista warned that I
need permissions and after accepting the warning I have no option to enter
my login to access the files.

You need to take ownership (and may have to do the reverse once you are back
in XP). Right click the folder, select Properties and go to the Security
tab. Click advanced, then set yourself as the new owner on the (what else?)
Owner tab, make sure to also check the box to replace owner on subcontainers
as well. Apply/ok your way out.

Also my user name and password on Vista is the same that on XP so I will
had to have access to the files without problems, right?

Only if this was a domain where rights to resources are determined by a
domain controller. On a workgroup rights are determined by the individual
installations. Your security descriptor in Vista is not the same as your SID
in XP. Your rights are limited to the installation that you are logged into.

Why I can access my files if I'm identified witht the same user on Vista
and the other drive is a NTFS system?

The above applies here. In order to access files/folders created by another
installation on the same pc, you need to follow the steps above to take
ownership of them. While there, you should adjust the "everyone" permissions
so that you don't have to repeat these steps when you return to the XP
setup.

Thanks Rick. Your explanations are very clear and informative.

But I'm surprised that I have to take ownership of a folder to get access to
an XP partition. Untill now I've never had to take ownership of any resorce.
I think this should be the last option to take privileges over the resource.

On XP or any network share when I try to access some resource on an NTFS
partition I'm asked for login and then I can get access to the contents.

I have another partition for my data that is outside of the XP installation
but I allways managed and created the files from XP. I will make some test
to see if I can work from both XP and Vista and what privileges problems I
have with it.

Best regards,
Angel.

Hi,

Remember, these files were created by another installation on the same
system. When you access across a network, the OS in which they were created
is running and controlling access to the files. What you are doing is
essentially taking control of files created by another system without
getting permission from that system first.

Mmmmm... I get the point.

I thought that as the file system on the other drive was also NTFS I could
access the files without worring about what system created them. Thanks for
the explanations.
