accesing xp files permissions

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.
