Konstantin,

Here is one method.

filename[i_] := 
  "data-" <> ToString[NumberForm[i, 3, NumberPadding -> {"0", ""}]]

filename[4]
data-0004

I generate a filename automatically by using

"data-"<>ToString[i]

however I would like it to be zero padded from the left (so all the 
numbers/names have the same length:

data-0000
data-0001

How can I do that?



Konstantin.
