Date: 2014aug28 OS: Windows Q. Where should my application save its working files? A. If its for a specific user:

C:\Users\<User>\AppData\Roaming\<YourCompany>\<YourApp>

If its for all users:

C:\Users\All Users\AppData\<YourCompany>\<YourApp>

And, of course, for user files:

C:\Users\<User>\Documents\<YourCompany>\<YourApp>

Its best not to hardcode c:\Users instead use GetProfilesDirectory() or SHGetSpecialFolderPath()
