Software programs usually grow with every release. Some of the remarkable products that made it from a tiny resource friendly application are Nero Burning Rom and Adobe Reader. Users who are fed up with those overweight programs usually flock to third party applications that provide a balance between resource usage and functionality. An alternatives for Adobe Reader is for example the popular pdf reader Foxit Reader.
Another possibility are so called lite versions of software suites. Both Nero Burning Rom (Nero Lite) and Adobe Reader have been modified by developers to reduce the program’s load times and storage requirements. Adobe Reader Lite has been recently updated to version 9.1 to catch up with the official Adobe Reader 9.1 release. Several plugins and other features that are usually not needed by the majority of users have been reduced from Adobe Reader Lite to make the software program more resource friendly. The basic functionality of working with pdf files has been retained.
The result is size decrease of more than 140 Megabytes compared to the official version of Adobe Reader 9.1 which uses 204 Megabytes of storage space after installation. Downloads are available for the English and other localized editions of Adobe Reader 9.1.

Adobe Reader 9.1 Lite speeds up the startup of Adobe Reader tremendously. It is a good alternative for users who prefer to use the original products instead of third party solutions.

I am not a big fan of unofficial mods to software. Sometimes it works just fine, sometimes it blows half system away.
Luckily I don’t interact with PDFs much so Foxit Reader is about enough. :)

1.2MB and it does everything i need it to
Great program! One point of note tho, this program does not not work correctly with the pdf preview handler on 64 bit systems with the reg fix applied. You will need to install foxit preview handler to get it to work!!
