Including header files using "" vs <>

when using #include to include header files，

If using <header.h>, the compiler will search the header file in the system header folder.
If using "header.h", the compiler will search the header file in the current folder first; if not found, it will search the header file in the system header folder.
In A.cpp, if using #include <A.h>，the following error message will show “fatal error C1083: Cannot open include file: 'A.h': No such file or directory”。using #include "A.h" can resolve this issue.
In a word，<> can be replaced with "", but "" can not be replaced with <>.
