Take a look at the 7zip SDK ... it may allow you to programmatically
create a spanned archive

I'll try this, thanks.
But I just wanted to know something also...
Spliting a file and then merging it back must work? Even with
"complex" files' types?
I'm asking this because I tried it with a ".txt" file and it worked,
but then, when i tried with an excel file with vb code inside, when i
opened it, it threw me a message like something was wrong, but then I
could see the grid's content, but the vb code wasn't there any more.
The file's size was the same than the original and all.
Then, when i tried it with a SharePoint's backup file (*.fwp) and
tried to restore a site through command line, i got an error saying
the file was corrupted or something like that.
Thanks again,

BTW, this is my code, maybe i did something wrong:
//Note: this.ext is a string property which represents the file's
extension.
