The limit is rather 65535 entries, isn't it?  The entries field has two 
bytes, and they are used fully.

Which programs are affected? InfoZIP Zip 3.0 and 7-Zip 9.20 seem to 
handle an archive with more entries just fine.  The built-in 
functionality of Windows 10 doesn't.

Besides, 64K entries should be enough for anybody. ;-)

Seriously, though: What kind of repository has that many files and uses 
the ZIP format to distribute snapshots?  Just curious.

That seems to be what InfoZIP does and Windows 10 handles it just fine. 
  If lower Windows versions and other popular extractors can unzip such 
archives as well then this might indeed be the way to go.
