Not exactly.

E.g.
- FPC uses a .fpc.cfg in your home directory
- Lazarus uses the directory .lazarus by default
- Firefox has its own directory in .mozilla/firefox

You are rather free here. The functions Ċ½ilvinas and I mentioned are 
returning a filename or a directory name (depending on the called 
function) in the .config directory (which is also used by other 
applications as well).

Not even that is a convention. As said you can use what you see fit. You 
can also use UTF-8 files or binary files (altough the user can't edit 
the seconds ones if you don't provide the tools for them).

But don't forget that the global config in "/etc" is normally read only. 
You should only create it during the installation phase (which is done 
by a administrator/root account and thus has the needed rights.

Sidenote: You can use the GetAppConfigDir/File functions on Windows as 
well and they will return you the directories where an applications 
should put it's configuration data normally (instead of the program 
directory).
