Mac and windows sharing - works but cannot open files

Hi all,

I finally bought my first mac, it's a Macbook pro with a 10.7.4 mac osx.

I (almost) succesfully inserted my mac in my network (one windows 7 pc and one linux ), each one can see the other and i can share files.

I also can copy and paste or create new files from the windows and the mac BUT:

- when on the win7 pc and open the shared mac folder (that is on the mac, I mean), I can see what's in the folder, I can write new files but I cannot open already existing files created by the mac

-when on the mac and open the sharing folder on the mac itself, I cannot open the files created by my windows pc.

- when on the mac I open the sharing folder that is on the windows pc, I can (yes) open files and modify them.

When I cannot open files, a message tells me that I don't have privileges (permissions I think, I am translating, the message is in italian...)

How can I solve it? Thank you for your help

 

Thank you for your reply.

Mac has one user let's call her "lisa"

Windows has one user "carlo"

On the mac I have added in the sharing permission settings a user "carlo".

Both "lisa" and "carlo" have permissions set to read and write.

I've just noticed that if I log in (on the windows side end) to the mac shared folder as "lisa", then when I am at the mac I can read and write at once, If I login (from the same win7 pc) as "carlo", then when at the mac I have to assign the mac shared folder and its subfolder "read and write" permissions to "carlo" in order to open and modify files.

Is there a way to tell the mac, when I create a file from my win to the mac shared folder, to set permissions for that new file also to lisa even if I am logged in as carlo?

 

Thank you Brian. Do you have a link?
