使用nsis安装程序复制文件夹，仅显示一个状态窗口，用于复制多个文件夹，一起复制多个文件夹

Question

CopyFiles of NSIS installer displays different "Windows Status windows of the copy operation" when copying different folders, but i want that only one status window is shown ,whether i copy one or two or five folders, like in Windows, when we select two folders , then only a single COPY STATUS Window is shown in which the progress of copy operation for both the folders is displayed.

Is this possible? I want to copy multiple folders, but show only one status window of the copy operation.

You can't do it with CopyFiles which only allows a single "from" path. Here are three alternatives:

• You could do the first, check the error flag to see if the user cancelled it and if it's not set use /SILENT on the second.

• You could use /SILENT on both (personally I never use CopyFiles without /SILENT as I don't want the user to be able to cancel it).

• If you really want to, you could do it with a direct DLL call - I don't know what the function would be and I expect you would need to construct a null-separated double-null-terminated string, all of which is fiddly with NSIS. I doubt that you'll think it's worth it. If you really want to do it this way, for a null-separated string use NullByte.nsh which we at PortableApps.com wrote for the PortableApps.com Launcher (for dealing with kernel32::GetPrivateProfileSection - we've since switched to parsing the INI file in pure NSIS as it's faster and not buggy; we will also use for dealing with services).
