Until Windows Vista I saved my application data into the directory where the program was located. The most common place was "C:\Program Files\MyApplication". As we know, under Vista and later the common user does't have rights to write under "Program Files" folder. So my first idea was to save the application data under the "All Users\Application Data" folder. But it seems that this folder has writing restrictions too!
So to sum up, my requirements are:

Your home directory is the only place where you can store files permanently. Applications typically store their configuration and automatically saved data in a file or directory called . application-name in your home directory. (Some applications save in groups, e.g., ~/.
To change directory permissions for everyone, use “u” for users, “g” for group, “o” for others, and “ugo” or “a” (for all). chmod ugo+rwx foldername to give read, write, and execute to everyone. chmod a=r foldername to give only read permission for everyone.
Some file permission examples: 777 - all can read/write/execute (full access). 755 - owner can read/write/execute, group/others can read/execute. 644 - owner can read/write, group/others can read only.
It's often good to use environment variables so you keep things more generic.
Vista has changed some things, with NTFS Junction Points. See http://www.svrops.com/svrops/articles/jpoints.htm
Anyway, using %appdata% should automagically put files in the proper place on xp/vista/7

There is no such location. Even on Windows XP (and probably 2000 as well) no such location ever existed; we just think it did because we all ran with administrative privileges. It is not until Vista forces us to run as limited user that we realize our incorrect assumptions. You're going to have to explicitly set the permissions on your directory.
