Is there a way to map a particular folder to memory? Say I have C:\somePath and I want that folder to be in memory at all times and maybe changes are dumped to HDD asynchronously without my notice. So this is more like a forced caching of HDD content in memory... For Windows 7 or any windows OS?
by default the windows cache manager does an OK job of managing cache size and will not add too much cache to a system. You can tweak the cache size but not the contents by default.
