I understood studying the filesystem api files are written to a specific directory(temporary or persistent), I wonder if it is possible to write to a accessible directory thing as "c: \ files"

Short answer: No. This has been covered many times before here. I explained more fully in my reply to JS Filesystem API: accessing JS FileEntry's on local system?.

In April 2014, it was announced on public-webapps that the Filesystem API spec is not being considered by other browsers. For now, the API is Chrome-specific and it's unlikely to be implemented by other browsers and is no longer being standardized with the W3C.
No. File storage is restricted to a sandbox. It can be temporary or persistent storage.
