Neither the Germans nor the Italians had any reason to conceal administrative records with no link to any kind of criminal activity. .
There was no "greater Albanian" policy on the part of the Italians, other than the annexation to Albania of southern Kosovo and Western Macedonia, which had already a majority of Albanians.
And even less on the part of the the Germans, who kept northern Kosovo in Serbia, despite its majority Albanian population.
Neither had the means to impose a policy of massive resettlement on the recalcitrant Albanians during a world war, neither had any reason to engage in one and there is no contrary historical evidence whatsoever.
You have been repeating a Serb lie and, like most Serbs, without even knowing it was one. And now you engage in fantasy, with even less plausibility, to rationalize your gullibility.
Whether you accept it or not, 60 percent what the Serbs say about Balkan history is false, and the proportion rises to 90 percent when the issue is Kosovo. That is, three times the level of mendacity of the Albanians or, for that matter, of the Croats. You can't be "even-handed" if you don't take those proportions into account but of course you can only evaluate them after studying the subject seriously.
And 80% of statistics are made up on the spot. Of course I realize that Serbian history is biased, that's why I gave you an unbiased link. No, you said, it is merely "even-handed" because it repeats Serb lies. Obviously you cannot prove that there wasn't substantial Albanian migration into Kosovo during WWII, just as much as I can't prove there was. But what I don't accept is your blind bias against any facts that may benefit the Serbian case. You are a propagandist. Or a true believer in something, I'm not sure what. Here's Wikipedia on Greater Albania:
During World War II, the dream of a Great Albania became a reality with the fall of Yugoslavia in 1941. Great Albania was established under Italian tutelage including most of Kosovo, Metohia and parts of Vardar Macedonia, Western part of Aegean Macedonia, and parts of Greek's Epirus
