Put your portable apps on a diet with AppCompactor

by Lee Mathews Oct 22nd 2008

I'm a big fan of John T. Haller's Portable Apps.com, and I was very excited by one of the apps that appeared in its RSS feed last night: AppCompactor.

It is, of course, portable, open source, and designed to integrate with the PortableApps suite. AppCompactor fuses UPX (for exe, dll, and other binary files) and 7zip (for jar and zip files) to compress portable applications. Not surprisingly, it's been used to package the other programs in the suite.

Using the default options, AppCompactor reduced my CCleaner portable folder to about 760k (about 40% its original size) and pummeled my ArtWeaver to trifling 3.1mb - a 10mb reduction. Both programs launched much more quickly from my Kingston Data Traveler, and they functioned exactly as they had before: no errors, no headaches.

AppCompactor can't work it's magic on everything, though. It didn't manage to reduce a single byte with FastStone Capture or Spybot, and it only reduced AdAware SE by 60kb. For curiosity's sake, I also tried portable version of Photoshop CS3 and Office 2003, and had little success with them either, saving only about 1mb on each.

Since it utilizes UPX, apps that were previously packaged using that type of compression (like the Gimp or Firefox) probably won't see an appreciable reduction.

Still, when it does work, it's fantastic. It's an incredibly simple way to boost launch times for some of your portable apps and provide extra megs of free space on your flash drive. A few megs might not seem like much on a 16 or 32gb drive, but space is space - and more is always welcome in my book.

I have been using PortableApps for a long time now and have not seen AdAware or Spybot available. Where are you getting these extra apps?

Where did you find (or how did you make) a portable version of Photoshop CS3?

Civiballs is a beautiful, soothing physics puzzle Time Waster

I have an absolute weakness for physics games, and while Civiballs isn't the strongest physics-based game, what it lacks in the physics department it makes up for a few times over in style and fun.

In Civiballs, you are presented with a few colored balls, and your goal is to get those balls into the same-colored urn on the level. The "civi" part of Civiballs is that there are 3 sets of levels to play, each representing a different civilization. While the civilization doesn't affect gameplay, the artwork for each level is beautifully themed to it's appropriate era.

To play the game, you are given only one tool - a sword with which to cut the chains that are holding the balls. The puzzle part of the game is in figuring out what order, and with what timing to cut each chain. Do it right, and all the right balls end up in the right urns, with no stray balls entering an urn (a no-no). Do it wrong, and you get to start over again.

Civiballs is not terribly deep on gameplay; the entire game can be completed in about 15 minutes. But if you enjoy this type of game, it will be a very enjoyable 15 minutes.
