System32 is the name of a folder used by the Windows operating system. The directory contains important files that are crucial for the normal functioning of Windows, so it should never be deleted.
What is the System32 folder and how do I open it?
All of the files and subfolders that make up the system32 folder are copied to the hard drive during the initial installation of Windows, usually to C:/Windows/System32/. This is true for both 32-bit and 64-bit versions of Windows.
Some of the system32 files are programs you may be used to using, but most are application files used for various purposes that you may never have opened manually.
Because many important Windows system files are located in system32, error messages often relate to files in this folder, particularly DLL errors.
