ISFILE is vile !

[Robert]

Code: [Select]

PRINT "It is ", BOOL$(ISFOLDER("C:\Windows\System32")), " that the folder C:\Windows\System32 exists."
PRINT "It is ", BOOL$(ISFILE("C:\Windows\System32\cmd.exe")), " that the file C:\Windows\System32\cmd.exe exists."

Result:

Code: [Select]

It is True that the folder C:\Windows\System32 exists.
It is False that the file C:\Windows\System32\cmd.exe exists.

Thanks Robert.

This corrected runtime corrects the problem for me (Windows 11 Pro).

Code: [Select]


int isfile(LPCTSTR FName) {
    static HANDLE Local_FileHandle = NULL;
    static WIN32_FIND_DATA Local_FindData;
    if (Local_FileHandle != NULL && Local_FileHandle != INVALID_HANDLE_VALUE) {
        FindClose(Local_FileHandle);
        Local_FileHandle = NULL;
    }
    Local_FileHandle = FindFirstFile(FName, &Local_FindData);
    if (Local_FileHandle == INVALID_HANDLE_VALUE) {
        return FALSE; // File not found
    }
    FindClose(Local_FileHandle); // Close the handle since it's no longer needed

    if (!(Local_FindData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)) {
        return TRUE; // It is a file
    }
    return FALSE; // It is a directory
}

Thank you. The fix works for me too.
