You can't create this file on the phone - you cannot create a file beginning with a "." in a linux environment (although I'm probably gonna get shot down for that one, it just seems to ring true from somewhere else is all), so it needs to be done in a Windows environment using Command Prompt and the mkdir command. There is probably not going to be a GUI coded to run WinSCP and SSH to create this directory locally on a windows machine using the WEP / WAP security on the WiFi routers and then transfer the file to a directory of your choosing o nthe phone!

Mate, the time you have spent banging on about this app you could have done all the above, set it up, explained to your "cute" girlfriend where everythihng is and how to get there etc etc. Come on man, pull your finger out and DIY.
