you need a program called ‘Winrar’ : install that program and unzip the .rar file you have..

A ar files is like a winzip compressed folder/file only you can chop it into bits.

Most likly the acrobat file is very small so would not have to be in bits like you would chop a video file to send it in two emails.

You need to make sure they are all togther.

Then rightclick the .rar file and go to wirar extract much like you would a winzip file.

Thats providing you have winrar on you pc…

Often packed on the disks on computer magazines or on the net should be easy…

Its what you would use to pack say a game and its files into a sort of spilt upable compressed folder then put back togther agin the other end…

just get hold on winrar

Theres a program called ExtractNow, whats so good about this programs is firstly its free and it can open rar, zip, .7z and many other types. Heres the link:-

Good Luck
