Well to change the file attributes, you can use inline assembly. The function
is:

To call:

AH    <--- 43h
AL    <--- 00h, Get file attributes
           01h, Set file attributes
CX    <--- New attribute (See bottom)
DS:DX <--- Pointer to buffer

Returns:

Carry flag clear if successful
CX = Attribute if get (See bottom)

Carry flah set if error
AX = 01h, Invalid function (file sharing)
     02h, File not found
     03h, Path not found
     04h, Access denied

6543210  Meaning
......1  Read Only
.....1.  Hidden
....1..  System
.1.....  Archive

A sample Quick C function would probably be like this:

void SetFAttr (char *p)  /* Not sure how to use pointers, I am an ASM progr.)
{

_asm {
mov ah, 43h
mov al, 01h
mov cx, 03h       /* Make hidden and read only  (0000011b)
push cs           /* May not   */ 
pop ds            /* be needed */ 
mov dx, p         /* Point to file */
int 21h           /* Set attribute */
}
}

I dont know if the above will work, since I havn't tried it yet (too busy), but
for know that should work. (I used it in one of my ASM programs). If you have 
any trouble, i'll write you the functions in C.
