Compress Data and Save Disk Space without any software

[FaMe FacToR]

Hy Guys! Here is a cool tip to have your data take less space then usual!
Windows comes with data compression technique, which very few people are aware of! i wasn't aware too! I found it out when i was fiddling with my data folder's properties. Then i saw the same thing in the disk drive's properties. i made the changes and it compressed the data so that i can use more space of the hard disk. While the best thing about the windows in-built compression technique is that no uncompression has to be done to use the compressed data! It runs like a normal data would! Great! Now here's how to compress your Disk Drive :

1. Right-Click on the disk drive and click on properties.
   
2. Then Check "Compress drive to save disk space" and click Apply and wait till the setting attributes complete. [See Screen Shot Below]
   
3. Then Click Ok.
   
4. Your Done.

Hey this is a great idea for disk compression but I have 3 questions!

1. This tool really compress the data & make you available more space for storage?

2. How much time does it take normally to compress a full disk say 80 gb with 70% data?

3. How will this compression affect on viruses & malwares?
I mean if i compress the data is it possible to consider that the data is more safe after compression?
