Hi Farouk,

When the FOpen() function opens a file successfully it returns a filehandle for the file but returns -1 when the file in question can't be opened.

There are various reasons that files can't be opened including: the file doesn't exist, the user doesn't have permissions or that it is already opened by someone else, etc.

Here's more information regarding the FOpen() function:

Good luck!!!
