Bonjour,
I've been using C++ on Windows and Linux for 20 years now. I offer FTP and other IP based engineering services to large coporations such as Ericsson , B.T, Thales etc.
FileZilla is "ready-to-go" open source SW. and has it's own Visual Studio(i.e. MS VC++ for IWndows) solution.
So, if you can outline for me - what kind of changes you want made, or what featuers you want added, I can look in to it and get back to you with a time and cost estimate.
Merci
