You know that the main game is always played in computer by file.
But if you have more knowledge about file type you can batter handle your system and your hard drive.
Sometime this is more handy when you transfer some file with your pen drive / usb drive and you need some more space, but physically it’s not possible to increase your hardware capacity immediately.
But you can do this by decreasing your file size.
You can understand it with this example -
I have two bin file
Total size of .bin & .cue files = 1.51 GB
After converting bin into iso
Total size of .iso files = 1.32 GB
Now you save = .19 GB / 194.56 Mb (where 1024 mb = 1 GB)
You can easily convert your bin file into iso with anytoiso free utility.
