Well, though my first language is not English, it is my preferred
language, which I've been speaking since I was about 4 or so.
And I was born in and grew up in the USA. Native Texican.

I was, well, shocked. OTOH, someone stated that extents and
fragmentation are not the same, as different extents may
well be contiguous on disc.

Hmm, anyone can explain what /dev/shm is? And why it's 62MB?
This is a dual-boot WinXP/Linux.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
