Are you sure you want to open it?

When a multifile HTML document is downloaded and opened every single
page opening (from the finder) results in the message

"XYZ.html" is a web application which was downloaded from the
Internet.
Are you sure you want to open it?


Is there anyway to mark such a group of files so that I don't
continually get the message?

Thanks,

Dale

This information is stored in some extended attributes on the files,
which you can look at (and delete) using the terminal.

Two extended attributes are used, but you only need to delete the second one:

com.apple.metadata:kMDItemWhereFroms
com.apple.quarantine

To delete the attribute, do:

xattr -d com.apple.quarantine <drag file to window here>

I took a screenshot of an Automator action that prompts for the files
to unquarantine, and calls the xattr program for you:
