If you are compressing a 7zip archive and creating split archive, do you need to wait for the entire compression process to complete before you start copying the completed pieces out of the folder?

I was wondering because frequently I am zipping several gig files and needing to ftp them, it would be useful if I could start the ftp transfer of the .001 piece while .002 was being created.

Once the file is written, it will not again be touched - I am not 100% about the first/original file as I have never tried to do this, but I am certain that other parts would be ok.

the 001 file is the one I was concerned about too. – Scott Chamberlain Apr 27 '11 at 20:28
