I have been playing around with exporting data for use on a webpage and have been using the Advanced Website template.

Because the database of my albums will be quite large, is there a way to only have new entries and an updated index file created?

I am trying to figure out an easy way to avoid having to reload up every file to the website. I can't say upload only files newer than ones currently there as all files will be newer. If I say to skip files that already exist, then the new index and some other files that have been updated will be missed.

Any suggestions??
