Question
What FILE Keyword represent in c language?

Answer
Hai Dear Ganesh !

 First of all let me confirm you that FILE is not a key word , perhaps its a  user defined data type defined in stdio.h , presenting you the following code to justify my answer !

typedef struct  {
       int             level;      /* fill/empty level of buffer */
       unsigned        flags;      /* File status flags          */
       char            fd;         /* File descriptor            */
       unsigned char   hold;       /* Ungetc char if no buffer   */
       int             bsize;      /* Buffer size                */
  unsigned char   *buffer;    /* Data transfer buffer       */
  unsigned char   *curp;      /* Current active pointer     */
       unsigned        istemp;     /* Temporary file indicator   */
       short           token;      /* Used for validity checking */
}       FILE;   

( Note :  Code Excerpt copied from stdio.h  )
While dealing with files in C programming , sure you might have came across this codes.

FILE * fp;

fp is a file pointer of type FILE , this file pointer is just to store the composite information about a file subject to manipulation , since you are a beginner definition regarding the FILE structure members are out of scope ,  if you wish to have please post me a follow up !

Thanks and Regards !
