I'd like to know if is possibile to sell a software that I create in Digitalpoint forum marketplace. If yes, what is the right section of forum to list my software? Of course I am the original developer and I have all rights to sell my software.
If you are talking about software for desktop computers (like Windows), no... they are typically just too large.
I too am an author of Windows apps, mine though are very small in size and all come with full source code. the smallest app I have is only a few kb, even a fully featured app like a Cover Printer I made 2 years ago is only 500kb in size!!! and I could optimise them even further and get them down to 100kb
