Windows 7 wanting to write various files to a blank disk. But where are they coming from?

Question

I just bought some DVDs from a shop, and I guess they are blank.

From the cmd prompt, I do D: (and if that were to work i'd do DIR). And when I do D: it won't work it says "incorrect function". Which is good that means here that it is blank(And not just blank it's not even accessible). That's from the cmd prompt.

But Windows 7 when I put it in, then this screen shows

If I then choose "Burn files to disc".

Then this screen comes up

And if I choose Next, then this comes up

So, it says "files ready to be written to disc" (so no doubt not yet written to the disk). And has AUDIO_TS, VIDEO_TS desktop.ini and memtest-86.iso

Why on earth memtest86.iso? is that normal for Windows to want to write that by default?!?!

I know what memtest is, it's an ancient program still used, that people run early in the boot process to test RAM. I find it surprising that Windows would want to stick an image file, iso file, onto the CD, along with other folders for a playable DVD.

And as a side note, I also find it strange that Windows wants to write those folders AUDIO_TS and VIDEO_TS when I haven't provided a video-playable DVD.. like

Answer 1

The VIDEO_TS folder showed an old movie.

It was because of files here(in this appdata windows burn directory), the files showed/show with DIR /A.

in

C:\Users\User\AppData\Local\Microsoft\Windows\Burn

e.g. this file

C:\Users\User\AppData\Local\Microsoft\Windows\Burn\Burn\VIDEO_TS\VTS_01_0.vob

I cleared within that directory and then it was fine
