I'm about to download OpenOffice, and I notice that the U3 version is 230mb and the portable just 65mb.
Are those two different distributions (the U3 being a fuller version and the portable is based on a smaller one?), or is it something concerning U3?
Well, part of that is that you're looking at the install size of the u3 version versus the download size of the portable one. Here's a more accurate summary:
OpenOffice.org for U3 2.0.1:
Download Size: 86MB
Installed Size: 230MB
OpenOffice.org Portable 2.0.3:
Download Size: 65MB
Installed Size: 177MB
Both are full, complete installs of OpenOffice.org (minus stuff like the UNO-Python bridge, QuickStart, ActiveX, etc). The U3 versions are always larger downloads and take up more size than the portable versions due to inefficiencies in the U3 format and platform. U3Ps are just ZIP files while the portable apps use a more efficient 7-Zip self extractor. And the U3P is kept on the U3 drive alongside the installed bits, which means duplication, which means lots of wasted space. Also, keep in mind that OO 2.0.3 is actually *bigger* than OO 2.0.1.
Sometimes, the impossible can become possible, if you're awesome!
Thanks for answering.
My drive is quite new and I'm just experimenting with U3, which indeeds feels a little "fat". I downloaded PStart (for U3!) and it's more comfortable and elegant.
Besides, many smaller apps that I use won't be available for U3 for sure. (Ztree, todolist, ...)
