Experience needed in SSH for modifications -- 2

I have a SSH form using FSW and timer, and it needs modification for zip & syncing 1). Needs to make files a zip file on host and no temp files via files mapped in memory Example: Load a file into a memory mapped file > Zip memory mapped file > Upload memory mapped zip file Download zip file into a memory mapped file > Unzip memory mapped file > Save memory mapped file 2). Also need to change SSH syncing events: Edit file system watcher and timer events Example: FSW should sync files and change events and timer should sync host change files I need this to get checked as well as how it syncs,--which has two phases: App start: if user is new (without files) a zip of the host's sync folder downloaded ( this method works but it seems that the zip file is lacking some empty folders ) App start: if the user isn't new (has sync files): recursions get compared for a sync ( this has no evident problems ) App runtime: change events are picked up by FSW; the timer syncs with the SSH host ( this syncing doesn't leave change files--it seems it doesn't work as expected now ) It's a relatively small source code on one form in vb.net .NET framework latest SDK Must have private IP VPN and accept award to be given app and server credentials
