I noticed that at some point that Xara has started duplicating files for the website I have been working on. In the folder, I'm seeing index.htm, index_1.htm, index_2.htm, etc.

Not all files have three versions, some have two. Why is this happening?

I would rather not upload extra unneeded files to my web server.

Also, can I just delete the extras from the folder when Xara is closed? And will it put them back when I re-open the program?
