10 Portable Applications To Consider - Part 3

Flash drives can do more than just store files, they can also be used to run applications on any computer. Which is why I’ve decided to list 10 of my favorite portable applications. The criteria used to select the applications is as follow:

  1. Free
  2. Requires no major modifications to run from Flash media
  3. Lightweight and small
  4. Useful and non-obstructive
  5. No major limitations

While not a complete list I’ve decided to list most of the applications in my Flash drive and give the list its own page www.linhost.info/usb-tools/. I will update the list as I find more useful software.
