F62ChunkChunk loads the ChunkChunk stack page on F6form submission.
It automatically formats the value of a field you specify to be suitable for a folder name. It moves this new value to a hidden chunkchunk field that you add to the form.
When the form is submitted, it loads the page with the ChunkChunk stack that you specify in the form GET URL action. It sends the value of the hidden chunkchunk form field.
The ChunkChunk stack appends this value to its folder setting which creates a unique folder for the files uploaded via ChunkChunk.
