Permissions on shared folders - who has the details

[Ken1]

I have recently been having issues (directing vitriol at my computer, running naked and screaming through the streets, etc.) and one of the aspects was regarding file permissions. So, I'd like to learn more about how Parallels, Windows and OS X interact in this regard. (For argument's sake, let's assume I mean the way it is INTENDED to work, as opposed to how it works in the 9344 update).

The Parallels documentation that I have seen is silent on this. All it says is that you can choose the shared folders to be read only or read write, an option set for each shared folder.

Well, that's fine, but the following questions (probably others) remain unanswered:

1. How does the selected setting intereract with whatever permissions are set on the file/folder within OS X?

2a. If I change the permissions via a folder's properties in Explorer, what is the effect both within Windows (virtual FS) and in OS X (native FS)?

2b. Can I alter the OS X file system permissions by changing the properties of the shared folder in Windows?

3. If I set a shared folder to R/W, does that override any permissions on the folder within OS X?

4. At what level (user, group, admin) does the read only or R/W attribute correspond with?

5. What happens when I change the native permissions on a file/folder in OS X?

You get the idea.

I'd appreciate any knowledgeable replies. Thanks.

As far as I know the Mac OS's permissions (essentially Unix) are quite different from the way Windows handles file permissions. So anything you change to permissions on a Mac file, including a file that is associated with your VM, will not be reflected in the Windows permissions.

So, I think the answers are: 1. not at all (if you mean "how does the selected *Windows* setting interact with whatever..."); 2a. no effect; 2b. no; 3. no; 5. the permissions change in OS X but not in Windows. 4 is beyond me, sorry.
