7-zip

Most of the people when think of file compression, two software come to mind. WinZip and WinRAR. Both of these software are good, but are not free. So if we are running them on our machines we better check if we are running the legal version.

Compared to this there is 7-zip. 7-zip is opersource and is hence free. It can do everything what commercial software do. Additionally you can unzip ISO’s as well as MSI’s. So if there is a small tweak that you need to do, or if you wanted to find some command line parameters of your installation media, us it.

You can download it from here. Very small in size. Has both CLI and GUI. I have been using it ever since I found it.

PDF Splitter

Many a times we need to split PDF files. We don’t have adobe full version to work with.

There are two ways we can do this.

a. Install and PDF printer and then print page by page. This is tedious but still workable.

b. A better solution is to download PDFSam. Please goto this site.

The beauty of this solution is as follows

1. It is free and open source

2. It promises what it does with no hidden catches.

So next time you want to split (or merge PDF’s) do use this. You may want to get some pages from a manual and send to a customer. You may want to split a huge book into chapters so that they consume less RAM while opening or less space on mobile devices.
