Unable to open file in C

Question

i am working in C and want to open a simple text file then perform some processing over it. My code looks like

FILE *pFile;
pFile = fopen("d:\\series.txt", "r");

if (pFile == NULL)
{
    printf("File not found or Unable to open file\nPress any key to continue . . ." );
        getch();
        return;
    }   
    else
    {
         //process here
    }

every time the condition becomes true if (pFile == NULL) so i am not able to perform processing on file.

I check that file exist in my drive with same name and its open properly when i double click on it

probably you don't have permissions to read it. Put it in d:\some_dir\ and try again. — Kiril Kirov

@Henno: Windows does not require capital letters for drives. In fact, Windows filesystems are overwhelmingly case-insensitive in general. — Lightness Races in Orbit

Try putting this inside the if block:

perror(NULL);

That should give a descriptive error message, so you know what went wrong.
