What is the Computer Operating System you are using? Windows? Mac? How old is your system?
The newer systems, and I believe Windows XP does this, will unzip a file when you double click on the file. Some systems are different, so you need to do some snooping around.
Place your mouse on the zip document and "Right" Click your mouse. You will see a list of commonly used functions which include 'copy' or 'properties' and you may have one that says 'extract all' Select that with a left click of your mouse and follow through with selecting and moving your file to where you want it to reside. If you leave it where it is, you have to find it again, which can be frustrating.
I am unfamiliar with Pulse, but you would have your document ready at this point for use with your Pulse Software.
I hope this helps. Pat
