Hi, any ideas as to why when I used set /a
totalfile=2,000+1,500 it gives me wrong answer. but when I
remove the comma it works fine. Do I miss something?

thanks in advance.

Yes, you missed two things, both taken from set /?:

1) ... the expression evaluator is pretty simple ...

2) the comma is an "expression separator", not a "thousands" separator.

So when totalfile received a value of 2, set/a was simply returning the
first expression from the comma separated list, as per the documentation.

ALF,
In the case of DIR (W2K) output it may help to use "/-C"

/C Display the thousand separator in file sizes.
This is the default.
Use /-C to disable display of separator.
 
thanks
