You want us to help you and yet you post your code elsewhere?
Come on don't be lazy. It's just a matter of copy and paste. And use code tags when you post the code.

What do you mean by the total of the job greater than 100kb? Do you mean that the file size should not exceed 100kb?

Use the File class. Open the API specs for it. It has a method for determining the size of a file. Just check your file's current size before adding data to it.

ok
but i dont have it is
can u write code

[kamsmartx]

i canot have API specs

[r035198x]

ok
but i dont have it is
...

What do you not have?

ok
..
can u write code

Some people think I can and some people think I can't ...
You'll have to write this yourself. We are here only to help you when you get stuck.
