You're showing me what most would call the code for the html page. My browser does a "Save As" as a web page, and if I open the saved file it opens in the browser and looks just like the web page. WYSIWYG said her browser saves as .mht, and other browsers probably have other preferred formats. Since only a few stone-age remnants and a few who are paranoid use text-only browsers, for most people it's extra steps to look at the code, which is one way to get the "thread id" or other info.
If needed, I can open the saved .htm file in a text browser, or view source in notepad, and see the code directly; but then you've usually got so much "garbage" that it's hard to read (for people accustomed to modern conveniences in their display of web stuff).
There's no argument about whether you can extract a lot of information by digging around in files saved by different methods. It's a matter of what gives you the easiest way of getting what you want.
If all you want is a list of the traced files, the printed "table of links" gives you a list of every link that appears anywhere on the page, with the "open and visible" URL that goes with each link and with NOTHING except the information about the links in the separate "Table of Links" portion of the printout. For some uses it's a fairly handy way of getting a certain kind of information, for those who don't have other favorite methods. It may only work with some browsers and with some printers.
My whole personal page saves as a 52 KB .htm file. There are 178 "href" items in it, for 66 threads traced, which suggests that the printed "table of links" would have about 3 lines per traced thread, or about 4 - 5 printed pages. Viewed in my browser, it's about 3.6 screens. The "code" for the page, viewed as text in a text editor or in a text-only browser would print 23 pages, which I'd have to sort through to extract only the threadid numbers if that's what I wanted. (I wouldn't be likely to print it. The page count is just for an idea of size.)
If you really want to burn up a lot of paper, you can also choose to "Print all linked Documents" from the same printer options tab, so if someone is foolish enough to try that, it should produce a print of their favorites page, a printed table of links on the favorites page, the complete printed text of all the threads they've traced, and (on some sites) a printed table of all links on the linked pages - probably along with an enormous amount of other garbage. I'd suggest NOT using that option (unless of course you're at the office using company furnished paper, and nobody else is likely to want to print anything for a while, and you're not likely to get caught).
It was suggested ONLY because of Joe's thinking that the threadid numbers might be useful. For purposes of this thread it's USELESS until Joe comes up with a way to use the threadid numbers to "batch detrace" files. It's a "feature" I ALMOST NEVER use, but I thought it might be of interest to someone who hadn't discovered it.
From the argumentative replies, one might think I'd revealed the archaeological age when you bought your last computer, or mentioned what a useless old fart everyone thinks you are. You should know that I wouldn't do that in a thread like this. I'd start a new thread where everybody would be sure to see it.
