Calculate file size

[_pi]

i send a 700mb file to my dialog and on button click all relevant parameters are passed to winrar.
when winrar is finished my function returns OK.
the parts are split into 100mb files (104857 KB)

what i need to know is how to generate the resulting segment file names.

test.part1.rar
test.part2.rar
test.part3.rar
etc.

i have a grey area for mathematics in my brain.
that is because i was not able to draw enough attention to it in school.

thanks.
