Persits.Upload question??

Hi there,

I was just wondering what is the difference between Persits.Upload and Persits.Upload.1 ?

I am currently using Persits.Upload and did a search just to check to see if you upload a file with the same name as one already on the server, will this automatically overwrite it?? It said it did by default, but then I noticed it was a tutorial on Persits.Upload.1 is this the same? (I couldnt find much on just Persits.Upload).

So my question is is there a difference between Persits.Upload and Persits.Upload.1? And if so, what? And will Persits.Upload overwrite files?? )

Your help would be very much appreciated,
Thannnkkksss,
