A friend just gave me a cd. What so peculiar about the disc is that it is a normal disc with size of 701 MB, but when I copy all the content to HDD, or looking at the files and folders’ properties, the total files size is 1.54 GB! How is this possible? The content of the cd has many same files but under different folders. I tried to copy the files from HDD back to 700 MB cd-r with Nero, and expectedly Nero complained about not enough space. All programs in the cd can be installed and working just fine.
Can someone here shed a light on this? Thanks.
