Did you ever see a compressed file with about 3 mb that when you extract it, it will pop a 15 mb file? If you have ever seen that file, you must be curious about how to do that right?
First of, is it that important to have a file compressed? the answer is of course! Imagine, if you have a slow internet connection, and then you want to send a file to your friend via 4shared or other upload site. the file was 15 mb, and you.ll have to wait about 15 minutes to successfully upload it. but if you.ve compressed the file, and the file is about 3 mb now, you.ve saved yourself 12 minutes!
i know 12 minutes sound not very interesting, but if you sit in front of your computer, waiting for 15 minutes, it.s very boooooring... so that 12 minutes makes our lives not so boring a bit. haha...
the compression software that can achieve that kind of compression is 7-zip. although other compression software can do that also, but 7-zip is totally FREE!! if you want to download just go to their official site here, and then to the download section.
But, remember, not all files can save up that huge chunk of size, the file that when you compress will become "tiny" is an application file (*.exe) because it isn.t precompressed. if you compress a .mp3 or .jpg file, the difference will not be so significant.
