In these days of extra large hard disks many try to copy huge files from a DVD/CD but find that can not even though there is plenty of free space on the hard disk. The most likely cause for this is not some sort of copy protection but that the file being copied is too large for the file system to handle. Microsoft Windows 8 allows you to format a hard disk in two different file system formats: FAT32 and NTFS. These file systems differ in the size of file they can handle. FAT32, for example, can only handle files up to ~4GB in size. When it was developed, that size file was almost unheard of but now, a DVD can have files that large or larger routinely. So, if you are trying to copy a movie from a DVD onto your FAT32-formatted hard drive it likely won’t copy as most full-length movies are files larger than 4 gigabyte.
