Forgive me for chuckling while reading this question, but you don't really understand the Usenet, do you?
It is technically not possible to edit/delete an upload/post on Usenet.
On the contrary, your upload/post will even be distributed among all providers/backbones and will remain available for as long as the retention of the providers/backbones (most major backbones have a retention of +5000 days).

The only possibility you have to get a post/upload be deleted is to raise a DMCA/NTD request with every provider.

Thank Tensai75 for your answer
I know this is a long shut
but from here
http://wiki.killfile.org/projects/usenet/faqs/cancel/
I understand that there is a "cancel" command that may be of help
I copied the relevant section at the end of this post

and also If I posted these files with the command line --obfuscate and random poster
and the files that was poster have 2-120 parts
for example from NZB file
5f412c94279r49b48d4868782bsgg1fe@ngPost
(
what is the chance that some one can download these files?
I accidentally post this files without password protecting them

Thanks

I'm not sure CANCEL is working with all provider and probably not replicated.
once posted, your file stays. that's the principle of usenet... like email or a text message, once sent, you can't delete it...
