Check if EXE, DLL, SYS and other files are 32-bit or 64-bit

Non-. net files by: Dumpbin.exe/headers File.exe (C:\Program files (x86) \microsoft Visual Studio 12.0\vc\bin)

. NET files by:corflags. exe file.exe (C:\Program files (x86) \microsoft Visual Studio 12.0\vc\bin)

Any CPU PE32 with 32BIT = 0
x86 PE32 with 32BIT = 1
X64/itanium (IA-64) pe32+ with 32BIT = 0
