This command is a real time-saver. Let's say you've been working on your website for the past two days and you are finally ready to upload your changes to the server, but you've worked on so many pages you don't want to go through the entire site and pick the ones to upload. You can have Dreamweaver do it for you.
First, expand the File pane using the Expand icon, shown at left (you should always expand the File pane before uploading to the server.).
Next, go to the Edit menu and choose Select Recently Modified. The dialogue box gives you three useful options, shown below. You can select any files you've created or modified in a specified number of days (the screenshot shows 2 days). You can select files you've worked on in a specific date range. Or, if you are using the Contribute option, you can select files worked on by a specific person.
Caveat! Dreamweaver often will NOT select images or documents you've added recently, even if you are linking to them from your recently modified page. You need to do that manually. And ALWAYS check your links after you've published.
