I was looking over the source code of a lua flashing app.  

Zinga - I was wondering, is there a way to write a whole folder instead of just a single file?


Any other snippets of info you could share on the subject would be much appreciated.  

Thanks again.  :)

I have no idea about LUA, but usually, in programming, you copy/flash/whatever files individually - you can't just set a folder, unless someone (or you) wrote a function specifically for that purpose.

You should be able to either:
1) Specify all the files you want to flash (eg copy+paste the lines of code)
2) Make the code go through all the files in the folder and flash them
