Read all the functions here!!!

#Save Text Files Anywhere You Want
You can save a text file anywhere you want !
You can also load and PARSE a string!!!
This parsing should make your entire goal great fun 
#FileHelper
You need to preface the above functions with FFileHelper::
#New Method of File Management
My code below is old
see my tutorial here for the new File Management functions
GFileManager no longer exists
