OK Guys.Most of you know me very well.I have a 4GB PNY that i used when i bought the laptop and Picasa did not load onto the PNY.
1.Is a 4GB large enough?
2.If so how can i wipe it clean?
3.When i plug an empty 4gb or larger,into my PC will i be able to load only Picasa? Rember i am a Techno. Idiot.

Good news.

Now get another flash drive somewhere. They sell these at computer stores, but also at big-box stores like Wal-Mart and Target. They often go on sale.

Do the same thing with that flash drive, and give it to a relative for safe keeping.
