Dennis E. Hamilton updated COR-21:
----------------------------------
Attachment: Extract-2015-01-10-0821-ZipFolders.png
The file Extract-2015-01-10-0821-ZipFolders.png is a WInZip scan of
zlib128-dll.zip.
Notice how the files are named within the Zip folder.
It happens that there are no directories inside a Zip. The Zip uses full path
names on its files.
The entries shown that appear to be for directories are special entries that
are generally only used on *nix systems to set directory permissions. These
are ignored on Windows (and Windows will not create an empty directory from a
Zip.)
There are many Zip-creating utilities that make these folder entries for no
particular reason, but they are in there.
The test output, which is what this is, lists the contents of the Zip in the
order in which it finds the items.
The WinZip utility I am using does not show finer detail when it tests a Zip.
7-zip provides even less information. I think part of the problem being seen
is in here, but it is not clear exactly what it is, since the other zip
downloads for the external libraries also contain directory entries within
them.

> 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.
