Eventually in this life, you're going to run into an archive file—a single file with multiple files stored (and compressed) inside it. They have different extensions, from RAR to ZIP to 7z and many more, and sometimes the program to open them costs you. Not 7-Zip. It opens all of those and more, and allows creation of new archives. It'll even encrypt the contents for safety. It's entirely open source.
The obvious choice of Office tools if you are a firm believer in open source, LibreOffice was a fork from the original OpenOffice years ago (itself an offshoot of StarOffice). Inside are word processor, spreadsheet, and presentations programs, a vector graphics editor, a math formula editor, and a database. It's a little more awkward to use than the desktop version of Microsoft Office, but you can't beat the price. Grab the LibreOffice Viewer app for Android to look at files.
Second, the term makes a lot of corporate types nervous. While this does not intrinsically bother me in the least, we now have a pragmatic interest in converting these people rather than thumbing our noses at them. There's now a chance we can make serious gains in the mainstream business world without compromising our ideals and commitment to technical excellence -- so it's time to reposition. We need a new and better label.
If you've got a Microsoft account, you have access to Outlook.com, the successor to Hotmail and Live mail and our Editors' Choice for Web-based email. There's still the Outlook program itself for Windows and Mac—it comes with Microsoft Office—but this free option is a perfect, minimalist, consumer-based webmail, complete with OneDrive integration. Interesting features include Sweeps, so you can, for example, delete all messages from one sender at once, and built-in chat—including Skype video chat. The version for iOS is particularly great.
Many people new to free software find themselves confused because the word "free" in the term "free software" is not used the way they expect. To them free means "at no cost". An English dictionary lists almost twenty different meanings for "free". Only one of them is "at no cost". The rest refer to liberty and lack of constraint. When we speak of Free Software, we mean freedom, not price.
Distribution of source code. One of the problems with most proprietary software is that you can't fix bugs or customize it since the source code is not available. Also, the company may decide to stop supporting the hardware you use. Many free licenses force the distribution of the source code. This protects the user by allowing them to customize the software for their needs.
With mobile apps and a Google Chrome browser extension—and that's it—Chrome Remote Desktop more than rivals even TeamViewer for providing plenty of remote access between systems (you can't use it to control a smartphone or tablet, however, only PCs). You can connect to all your computers and devices that are on the same Google account, or get a code from others for a true remote session. You don't even have to have the browser running to get access to the PC. What's lacking is file transfer between systems, but you can get around that using Google Drive.
Freeflys: Another strong contender in the freebies space, Freeflys has appeared on NBC’s Today Show, The Doctors, Fox News and a handful of other media outlets. Similar to most of these sites, Freeflys utilizes email alerts to tell users about free-sample offers as they happen. The site also allows you to search for a specific product with the handy search bar.
