How To Get System Folder Path(C:\Windows C:\Program Files) in Windows using C++?
提问by sxingfeng
I am programming in c++ MFC,
我正在用 C++ MFC 编程，
I want to get "C:\windows" "c:\program files" folder path.
我想获得“C:\windows”“c:\program files”文件夹路径。
Sometimes user may setup windows in other folder such as c:\windows0.
有时用户可能会在其他文件夹中设置窗口，例如 c:\windows0。
Is there any API to get absolute path of the windows and program files path?
是否有任何 API 可以获取 Windows 和程序文件路径的绝对路径？
Many thanks!
非常感谢！

For the Windows folder:
对于 Windows 文件夹：
TCHAR windir[MAX_PATH];
GetWindowsDirectory(windir, MAX_PATH);
For program files:
对于程序文件：
TCHAR pf[MAX_PATH];
SHGetSpecialFolderPath(
0,
pf,
CSIDL_PROGRAM_FILES,
FALSE );
Where MAX_PATHcomes from the Windows headers and will guarantee the buffer is long enough for the longest (non-UNC) path.
哪里MAX_PATH来自 Windows 标头，并保证缓冲区对于最长（非 UNC）路径来说足够长。
Also, note that SHGetSpecialFolderPathcan be used to retrieve other "special" folder including the Windows folder just by replacing the third parameter to any from this list.
另请注意，SHGetSpecialFolderPath只需将第三个参数替换为此列表中的任何一个，即可用于检索其他“特殊”文件夹，包括 Windows 文件夹。

On Vista+, SHGetKnownFolderPathis the replacement for SHGetFolderPathand SHGetSpecialFolderPath, although you can continue to use the older functions if you need backward compatibility to older versions of Windows.
在Vista +，SHGetKnownFolderPath是替代SHGetFolderPath和SHGetSpecialFolderPath，虽然可以继续，如果你需要旧版本的Windows向后兼容使用旧的功能。

Most of these come from SHGetFolderPath, but GetSystemDirectory() returns the absolute location of C:\Windows\System32. Don't use GetWindowsDirectory(). It doesn't do what you want anymore.
其中大部分来自 SHGetFolderPath，但 GetSystemDirectory() 返回 C:\Windows\System32 的绝对位置。不要使用 GetWindowsDirectory()。它不再做你想做的事了。
