text reader writer as a class. Write anywhere in any folder.
you can set the file to overwrite and or append, not sure if overWriteFirst is necessary. But everything works.
just make sure to call close() after writing, other wise move the close method into the write methods.
setLocation();
this will populate the folderPath, fileName and ext of the file.
there is then a counter currently set to a maximum of 100 files. This is to increment up if a file with the matching filename is found based on the starting params you have chosen.
Overwrite will simply overWrite any file of the same name and keep saving to that same location.
