So to be perfectly clear: If I export my Construct 2 game with node-webkit i can code-in node.js file-access routines to create a C:\GAME\SAVES directory with
fs.mkdir(path, [mode], [callback])
then save into this directory a file called savegame.dat with
fs.writeFile(filename, data, [encoding], [callback])
and all relevant functions like append, read, etc..
So the EXE compiled with node-webkit has full access to the drive?
If this is so I only need to find an installer that installs my Construct 2 game to the user given path: for example C:\Program Files\C2Arcadegame
then file-access wise we are in the best situation.
