What is the Best Way To Upload "Thank You Page" Files?

Hello Warriors,

Could someone help and guide me on this scenario i am
stumpling upon :confused:

@ the moment, i am considering to decide what Payment Processor
Button to use, maybe PayPals or the 2Checkout.com to deliver
and pass my Download Thank You Page to customers. i will decide this soon!

Ok, So i have a one 'Download Thank You Page' ready to be passed to
customers when they choose to Buy it Now from my main sales pg.
This Downloud page has all links in categorical order
embedded to facilitate download of my products which is consisting to equal of:
50 individual files@ a total capacity of about 1.5GB.

Now all of these 50 files and Download Page above, i
have put organised order into a Folder on my Desktop which i
named 'Customer Page'

And so, i have cPanel Hosting that facilitates Public.HTML
folder for Upload. And i need to test Thank You Download pg linkages
on my hostings server side - in a 'online' test environment as you will appreciate.

Now in terms of considering to the set up of a Payment Processing
on my Sales Page...,

Do i upload all the 50 files and Thank You page etc in the Customer Page Folder
**individually** into my Public HTML Folder - Will that not look messy and
cluttered up in the Public Folder? And potentially cause issues?

Or...

Do i just Upload the complete Customer Area Folder folder
as one complete entity into my Public HTML Folder rather
that individually on file by file basis?
So it will be neatly sitting alongside my Squeeze Page and
Main Product Page.

So please, which is the best and efficient way to upload this for
the purposes of integrating my Download Thank You Page
with a chosen Payment Processor which i will be setting up soon,
such as, for, e.g. Paypal, 2CO etc?

I most welcome and warmly appreciate some guidance and
help from members of the community, thanks.
