Build Ok!, problem's source is my typo. Fixed, but not tested. Build in to VC2010.

P.S.

Как обычно - одновременно делать работу, и писать бумаги - какой злой дух придумал сиё наказание!?:( Да мне легче дивизию чертей наловить, обстричь, рога поотшибать и вместе с шерстью сдать в счёт госпаставок - в Аду тепло, не замёрзнут.:)

Tested - Ok! Additional test - download FreeBSD 12 STABLE images - it's not so easy to get to them. on the servers of the daemon, a cascade of inter-server symlinks is used - the images lie on a cluster of NFS servers and this is a good test for "have we not broken the work with symlinks and FTP?" and work with complex server systems.

The same cascade, for example, does not allow to see the real size of the file ftp://ftp.freebsd.org/pub/FreeBSD/ports/ports/ports.tar.gz - through the symlink it is addressed ftp://ftp.freebsd.org/pub/ FreeBSD/development/tarballs/ports_current.tar.gz and if you don’t know this, you won’t find the file.

Whats new?:) If try VC++2010 build and open for update 7-Zip archive in to local FTP have crash in to GetFilesW():
