A strange message has appeared twice recently in my Clipboard Viewer. I paraphrase: "Contents are stored in binary data only and cannot be viewed in Clipboard Viewer. You can try pasting contents into a document." In each case the item in question was a long Facebook comment, as it so happens. However, in this question, I will only refer to the second, most recent comment (as little follow-up was done after the loss of the first, though the circumstances were identical). I had been highlighting and copying this comment at regular intervals as I went along, typing as I was directly into the website. Then the Facebook tab I was using crashed, immediately recovering itself (I was using IE8), my text lost however. But most of the text should have been 'on the clipboard'. It was - or something was - but was, as stated, unviewable in Clipboard Viewer. And I only looked at the Viewer because I could not paste back into the FB comment box. Nor, following the suggestion on the viewer, could I paste anywhere else (stupidly, I did not try Notepad, but did try Word, Paint and Wordpad). So, I went on a hunt to find something which might display the binary data as readable text. But, I needed to find where the data was. Bringing up clipbrd.exe itself just produced the programme's script in the various formats (Hex., etc.) provided by a free gadget I downloaded, my FB comment nowhere to been seen there (though various bits of readable text were - including the message quoted above!). After a LOT of googling, I found several blogs where the same question as mine was being asked, the general conclusion being that data saved through Clipboard sits in an unidentifiable place within the RAM or the Page File. No one - including an MS staffer - could say more really than, "If clipbrd.exe knows where it is, that's good enough." I should mention that a clipboard saving gadget that I use had no record of the lost comment. My guess is that the announcement about relapse into binary data on the Viewer really just meant "Gone. Wiped." But, it would still be useful to know where clipbrd.exe stores its data. Maybe it picks and choses, depending on other variables (type of document, size, amount of free memory, etc.). However, if it knows where its saved item is, it should be possible for it to tell someone else too, logically.
The moment has passed (and in future my longer FB comments will be written into a document first!). But any firm knowledge on this topic would be read with great interest.
