A CD software release can contain up to 700 megabytes of data, which presented challenges when sending over the Internet, particularly in the late 1990s when broadband was unavailable to most home consumers. These challenges apply to an even greater extent for a single-layer DVD release, which can contain up to 4.7 GB of data. The warez scene made it standard practice to split releases up into many separate pieces, called disks, using several file compression formats: (historical TAR, LZH, ACE, UHA, ARJ), ZIP, and most commonly RAR. The original purpose of these "disks" was so that each .rar file could fit on a single 1.44 MB 3½ inch floppy disk. With the growing size of games, this is no longer feasible, as hundreds of disks would need to be used. The average size of disks released by groups today are 50 megabytes or 100 megabytes, however it is common to find disks up to 200 megabytes.
