It adds a menu item to the right-click context menu, allowing you to create a file list from any folder you right-click. It has a set of options that allow you to change what sort of information is stored in the output text file.
I haven’t used it, but Paint.net has been getting good reviews for a free image editor.
I recommend, if you are looking for free software, you take a look at Gizmo’s Freeware. It’s a great place to find reviews of the best free software out there. Each category of software is personally reviewed by its respective editor (of which we have over 60 editors contributing), so you are getting a real perspective on the software and not simply a rating.
Why is it impossible to have a conversation like this without some self-important freeware fetishist feeling the need to explain the difference between “free as in speech” and “free as in beer,” as if no-one else knows the difference? Do you want to give us a lecture on open-source code also?
As you noted in your own pointless post, for the OP’s purpose the distinction is basically irrelevant. Hell, the OP himself did not ask for “freeware,” he asked for “free software.” You knew what he meant, everyone else knew what he meant, and he himself made clear that he was happy with the answers that he was getting.
There are, in the world of software and coding, important differences between things like “freeware” and shareware," between open source and closed source code, and between all sorts of different licensing agreements. But it’s really not at all relevant to this thread. Furthermore, if the OP did want to know the difference, your post wouldn’t have even helped him, because you were so caught up in playing “gotcha” that you never even explained the difference for people who don’t know what it is.
