The best free open source software for Windows

InfoWorld - To many, free open source software and Microsoft Windows seem to be mutually exclusive. After all, the open source development model is most closely associated with the Linux OS and, to a lesser degree, various Unix derivatives. So when you mention the two together, you often get some rather strange looks. This is a shame because there exists a growing landscape of compelling free and open source solutions just waiting for the intrepid Windows user.

You probably already know one of them well. Firefox has long stood as a prime example of how the open source development process can work to deliver a first-class solution that rivals, and in many ways surpasses, the best that the commercial side has to offer. However, it would be a mistake to make that arduous (for novices) trek to Mozilla.com and stop there. Over the horizon are many more FOSS-on-Windows treasures waiting to be discovered, including tools that can improve your productivity, expand your lines of communication, and help keep you safe from threats along the way.

Get well-connected with FileZillaFileZilla is one of those essential Internet tools that you just can’t live without. A full-featured Windows FTP client, FileZilla makes interacting with FTP sites an efficient, productive process.

I’m particularly fond of FileZilla’s handling of batch transfers. I mostly use the program to update various remote Web sites I manage, and I find its ability to process large sets of modified source files to be especially helpful. Most operations are a simple drag-and-drop affair. However, when I need to exert more control over the transfer, I can tap into FileZilla’s dizzying array of configuration parameters -- for example, using a time zone offset to synchronize files from a distant location, a convenient feature when you live on a remote island that’s nine hours ahead of your servers.

FileZilla truly is a Swiss Army Knife of a transfer program, and that is ultimately its undoing. In their quest to cover every conceivable FTP scenario, the developers have created a bit of a Frankenstein product, with multiple mixed UI metaphors clashing with one another. For example, the program (now in version 3.1) sports an archaic-looking, Windows 3.x-era toolbar. However, most of the more powerful features and options are buried inside its old-school menus and tree-view-laden dialog boxes.
