Hundreds of asp files on remote server - can anyone help me?

I am no genius in Dreamweaver but had until recently been able to make a homepage for a small publishing firm. I subscribe to Adobe CC and thus get always newer versions. I made our homepage on Dreamweaver CS3.

I have downloaded both CC17 and CC18 but have returned to CC15.

For some days I have had BIG problems putting especially the index and the file containing all our books. All putting is unsuccessful. I can upload the book sites without any problems.

Only today I realised that on the remote server HUNDREDS of asp files have been created. For the index "index10.asp  up to "index131.asp" and for the file containing all books HUNDREDS AND HUNDREDS OF "nmd-hu-shoes-XXX.asp" files where "XXX" means any figure from 10 up to nearly 4000.

Why does this happen?

Earlier I always ensured that the local and remoter server were fully synchronised, but unfortunately I have skipped this important issue for a long time.

Can I delete all these asp files on the remote server as well as the index and file containing all the books and put the index and the file containg all the books from the local server?

I am somewhat ashamed of all this mess thus revealing I am no advanced Dreamweaver user (my competence is with InDesign).

Please help me.

THANKS in advance.
