Dennis E. Hamilton commented on COR-21:
---------------------------------------
OK, so it is about the organization of the zlib128-dll.zip.
Note that the extract of zlib128-dll.zip to external\download\T\
is in a single operation. That is, the creation of T (which does not exist at
that point) and the subfolders all happen as part of the single copy operation.
How it is done internal to the Windows shell copy operation is more elaborate
than that, but there is only one request from the extract_downloads.bat script
for each extracted zip.
So there is nothing to set permissions at the time the effective "Extract all"
from the Zip is requested. Afterwards, there is no writing into T\. The
useful stuff is copied *out* of T\ and then T\ will be deleted completely (one
hopes) just before the next Zip extraction is done.
I need to muddle on this a bit more. We may have to require a Windows-native
unzip utility simply to get around these problems. Because of differences
among implementations, we would have to choose a specific one that we can use
and work around any quirks like this one.

> Peter reported failures of the extract_downloads script when operating on a
> share from within a Windows 7 VMware Guest.
> A similar problem has been replicated with a Windows 10 Guest on Hyper-V.
> It smells like some sort of race condition.
> Some use on shared drives work, others fail.
