I'm using Shell API to copy a folder with files.
SHFILEOPSTRUCT sf = {0};
sf.wFunc = FO_COPY;
sf.hwnd = 0;
sf.fFlags = FOF_NOCONFIRMATION | FOF_NOCONFIRMMKDIR | FOF_NOERRORUI | FOF_SILENT | FOF_NO_UI;
sf.pFrom = "C:\\Users\\Sergi0\\AppData\\Local\\Temp\\untar.temp\\000\0";
sf.pTo = "F:\\\0";
// both pFrom and pTo are double NULL terminated, I have rechecked it
int err = SHFileOperation(&sf);
Everything works fine, folder is copied to the drive F: The problem is that messages
internal\sdk\inc\wil\filesystem.h(820)\windows.storage.dll!7684045C: (caller: 7676413A) ReturnHr(2) tid(660) 80070057 Incorrect parameter.

are printed in Visual Studio debug console. There are 100 files inside folder 000 and 100 messages were printed.
Should I be worried about these? I'm using VS 2017 on Windows 10.
UPDATE I have tried with another device, I see the same errors in both VS2017 and VS2008. But, there are no such errors with generic flash drive. So it seems it has something to do with mass storage implementation on the devices I use. I didn't find file filesystem.h anywhere in SDK.
You don't need to worry about these messages. The copy engine is trying to get information about the destination directory (F:\) but it turns out that it's not a directory; it's a drive. The error is returned ("Silly copy engine, that's not a directory."), the copy engine says "Sorry," and everything proceeds normally.
Sorry for creating unnecessary alarm.
