That depends on how you are opening the file to begin with.  But generally
no, the file is not loaded into memory, it remains on the hard drive and the
OS only loads data into memory when needed/requested.

For what purpose exactly?

That is a lot of data to load into memory at one time.  If you're only
reading the file, but not modifying it, then have a look at using a memory
mapping instead.  Look at the CreateFileMapping() and MapViewOfFile()
functions.
