not sure what is going on with link?
I bookmarked the page.

A bookmark is a local shortcut, not the actual file. As you can see from the "C:" in the link you posted, the file is located on your hard drive.

If you are trying to post a document such as a datasheet or app note, find it on the web and post the URL.
