OK, that worked --with a minor modification, the root folder is not "Main", "Main" is just another catalog, but thanks.

I really like your software. However, I do think one should be able to exclude files by extension. As an end user, I HATE being forced to edit copy scripts by hand and resort to something like:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>Class</key>
	<string>Include</string>
	<key>Description</key>
	<string>Excludes Lightroom Previews.</string>
	<key>Directives</key>
	<array>
		<dict>
			<key>Directive</key>
			<string>exclude</string>

			<string>*.lrdata</string>

			<key>Item</key>

	</array>
	<key>Include Directives</key>
	<array/>
</dict>
</plist>

I had to do it by hand because the command panel and its filesystem browser are really impractical when you need to use wildcards.

Moreover, if I try to save this script as a separate "Exclude LR Previews" and then include this script in my main backup script, SD hangs indefinitely on the "Copy Files" phase, with all counters remaining on "0". If I just use the path you suggested, everything works.

OK, that's it. Sorry for the rant and congratulations for a great piece of software.
