I've downloaded Windows 10 Disc Image from microsoft.com recently. I mounted it using Archive Mounter in Ubuntu. And I saw just a hidden folder "." and an empty "README.TXT" file in the root.

Files screenshot

ls -aR result is

.  .  ..  README.TXT

The disk content looks strange to me, I have not seen this before, and I think it may be some kind of protection from file browsing. Because when I try to enter "." directory I remain in the same directory. I know that "." has a special meaning: What do “.” and “..” mean when in a folder? - and this's probably a reason why I can't enter "." directory.

  • Is it really a trick from MS to hide disk internals?
  • Do you know any anti-trick? =)

They don't match anything on the internet, but MS MVP says:

The checksums are all over the place, you are not gonna find one thats the same to match what you downloaded.


I've redownloaded the disk image and now its size is 4.7 GB and its checksum matches the one provided by @Ignacio Vazquez-Abrams. The above question is still actual: when the image is mounted using Archive Mounter its content looks odd, but when it's "burned" to USB I can see installation files and browse freely.

    Did you read the other file? – Ignacio Vazquez-Abrams Dec 25 '17 at 8:55
  • @IgnacioVazquez-Abrams, README.TXT? It's empty... – naXa Dec 25 '17 at 8:57

    Strange. I downloaded the Windows ISO previously as well, and it shows up as expected. Is there a checksum you can verify against? – Ignacio Vazquez-Abrams Dec 25 '17 at 8:57
  • @IgnacioVazquez-Abrams please, see the edited question – naXa Dec 25 '17 at 9:22
  • If your checksum doesn't match anything (I checked mine [Win10_1709_English_x64.iso, 1ad928cfef439f6aa4044ddc3a96b0b6830bdd0f] and got a large number of matches) then I would suspect that the image is broken. – Ignacio Vazquez-Abrams Dec 25 '17 at 9:25
