Was auch immer das sein soll.
Wie schon erwähnt wurde, fügen ordentliche Browser/Programme beim Download an Dateien ein Flag "wurde runtergeladen" an,
was dann bei EXE, ZIP uvm. später beachtet wird und wo diese Dateien dann gesondert/zusätzlich geprüft werden.
Und "ordentiche" Entpacker fügen dieses Flag wiederum an alle Dateien an, wenn die ZIP jenes Flag hatte. (7-Zip hält sich aber nicht immer schön an vorgeschriebene Windwowsgepflogenheiten)
Off topic "just a little more details on this part":
It is not a flag, although it is shown as flag in the file property with Windows Explorer
But in fact it is an Alternative Data Stream (ADS), a hidden stream (not really hidden but simply not visible out of the box) attached to a file and specific to NTFS, this "flag"/Stream in particular is name specified and fixed as "Zone.Identifier:$DATA" and its content is full ini file structure, to see it you can use "more" in console like this
Zitat:
E:\Download>more < battery-historian-master.zip:Zone.Identifier:$DATA
[ZoneTransfer]
ZoneId=3
ReferrerUrl=https://github.com/google/battery-historian
HostUrl=https://codeload.github.com/google/battery-historian/zip/refs/heads/master
E:\Download>
As seen above my browser added the download link and the referrer, this is not the case with all the application that do that, also the ZoneId number is coming form Internet Option in Windows.
ps: yes you can see your old downloaded files original links
so stick to downloading video from YouTube or remove the links
