Xslimmer is an application for Apple's Mac OS X developed by LateNiteSoft. The software has been discontinued by its developers.
Xslimmer reduces the space occupied by applications on your Mac.
Xslimmer reduces the amount of space on your hard drive your programs require, once installed, eliminating all the files that are unnecessary for it to work.
How Xslimmer works consists in eliminating the surplus code, depending on the kind of Mac that you have. This means, that if you have a Mac with Intel, it will eliminate the code that is necessary for PowerPC, and vice-versa.
Purportedly, the recovered space is significant. For example, according to the developers Google Earth 4 shrinks from 101 MB to 52.8 MB (a 47% reduction).
The developer's stated goal of Xslimmer is to achieve size reduction without compromising functionality.
