I’ve been using export to disk successfully, but I have one question: when I updated a few of the popups on the site, instead of uploading the whole site (32 MB), I tried just uploading the files that changed. When I did that, the popups didn’t change on the web version. Is the only alternative to upload the whole site each time?
there’s a thread here that goes into the details of how Sparkle generates the files:
The TL;DR is you can get away with transferring only changed files (by looking at their date), but it’s probably best to use Sparkle’s built-in publishing.
