Good idea. But I talked about very simple algorithm... My hope was in
that fact, that my idea is only starting point...

But I don't see any difficulty. You can get name once you found this
character or "head" of string.
BS> 3. You can't make any assumptions about the length of the extension,

Of course ! Don't think I'm so fool ! But, I think, better give hint to a
man and let him boil his brains himself.
My variant. It should completely work.

#include
void main ()
{
int position = 0;
char Filename[8];
char String[128];
..... // get your string
int i=0;
if(Filename[0] != 0)
while (i !=0)
{
if(String[i] == '\') position = i+1;
i++;
} // We will move position until we find last '\'
// Next cars sould be filename with extention
int j=0;
while(String[position] != '.'|| String[position] != NULL)
{
Filename[j] = String[position];
j++;
position++;
}
Filename[position] = NULL; // Lock vector by NULL character.
}
-------------------
So, we can do it movig forward as well, as backward :) At the first step
we find last name (last name will be name of file) and we wil get it :)
If we need extention, we can after second step using 'position' get
extantion.
