Flash drives (a.k.a memory sticks, usb drives, usb keys and thumb drives) make it increasingly easy to take your data on the road. With gigabytes of storage available, you can take all of your spreadsheet, presentation and document files wherever you go.
Unfortunately, your data isn’t any good if you don’t also have the appropriate applications. Public computers at libraries, internet cafes and hotel lobbies often have only a browser installed. Business offices will have a full suite of applications, but not everyone uses Microsoft Office. And even if they do, the applications may be locked behind password protected security systems.
Using another person’s computer also presents a security risk. Any time you use an application, you leave behind traces of your visit. Productivity software often will store older versions of files as a courtesy to the user. That courtesy can become a real threat if you have proprietary information.
The good news is that, as the capacity of flash drives continues to increase, it has become increasingly easy to take simply take your applications with you. And in doing so, you dramatically reduce your security exposure.
Running software from your flash drive, however, is not as simple as installing Office to the stick instead of to your hard drive. Flash drive portable applications need to be able to run entirely off the drive, without installing anything on the host computer. They can’t rely on the host having Visual Basic, .Net or Java. They can’t be location dependent, because when you plug your drive into a host, you can’t control what drive letter your device will be assigned. And settings and files also need to be stored on your portable drive, not on the host.
Fortunately, there are an increasing number of applications that meet these requirements. Even better: the best of these are FREE.
Portable Open Office
Open Office is the amazing, free, Microsoft Office compatible suite that includes a word processor, spreadsheet, presentation tool, drawing package and database. While some of the interface is a little different, for the most part, if you know how to use MS Office, you know how to use Open Office.
While Open Office was designed to run on desktop machines, there’s also a “portable” version that runs off your flash drive. The applications take up 144MB installed, so you’ll need a bigger drive, but these days, that’s no problem.
Portable Firefox
Firefox is another desktop application that has made its way to the portable world. Whiles any computer you use will have a browser, Portable Firefox will make your life easier in several ways:
First, it allows you to import your bookmarks from your desktop version. So when you are on the road, you are never at a loss for the url of that important site. Second, it lets you use all of the plugins that you have become accustomed to. And finally, it won’t leave any traces of your web surfing on the host. No one will be able to see your “history”, or a cache of the sites you visited.
Photofiltre
If you need any proof that big things can come in small packages, you jut need to take a look at Photofiltre. Its a full featured painting / photo editing package that fits on, and runs from, a flash drive.
Foxit Reader
The Portable Document Format (pdf) file has become the defacto format for transfering documents between users while retaining formatting. Foxit Reader is a small, fast pdf reader for your flash drive.
PStart
To manage the applications on your flash drive, PStart is then ideal launcher. Because it uses relative paths to launch the applications, PStart doesn’t get confused when the drive gets assigned different letters on different computers. To add applications to the main menu list, you just right click. PSmaart also offers search and not taking functions.
