Copy error to a VPN network directory in TC8, in TC6.56 OK

[pkr67]

I'm connected via Cisco VPN client to my company's network.
When I copy file aaa.rar (containing 18 files) to network disc (not mapped, \\10.33.44.55\Public), I get this error:
Error: Cannot write \\10.33.44.55\Public\aaa.rar
Please remove the write protection!
Skip Retry Abort

While copiing, the progress bar shows 0%, then 17%, then 34%, then the error.
If I click Abort, there is the file aaa.rar on \\10.33.44.55\Public, it has it's right size (3 127 456 B), but icontains only part (4) of all (18) files, it's corrupted.

When I use TC 6.56, progress bar shows 0%, 1%, 2% .... and everyting works well without any error.

In TC8 Options I have checked "Use standard copy method (recomended)"

Is there any way to make this working? It's bothering to switch between TC 8 and TC 6.56...

Thanks!

TC 7.5x uses CopyFileEx by default, while TC 6.56 uses a loop of ReadFile and WriteFile. It's very unusual that the built-in Windows copy function fails.

Just uncheck the "Use standard copy method (recomended)" to use the old method.
