There are things in life that I truly appreciate. One of them is "Free" and the other is "Portable". Lupo Pensuite is a compilation of freeware portable applications available for download. The file size is approximately 220 MB for the download, and 340 MB in use. This will easily fit on a flash drive.
Checkout the website here.
Here is their description of the suite:
"Lupo PenSuite is a completely free suite of portable programs and games. This Suite is designed to simplify the user's life, by collecting the best suites and portable applications available on the Web.

Here you can see list of all the programs in the package. What's nice is that you can click on the program and get a description, rating, and a screen shot.
