File Compression

Large files can be stored either in their original format or in a compressed format to save space .Different types of file compression are used for different types of files, such as text, graphics, and audio. You usually can reduce a large file by at least 50%, depending on the type of file and the type of compression.
In case of audio files, for example, the MP3(Mpeg audio layer3) format can be used to reduce audio files by as much as 90% to 93%. Bigger is never better when you are trying to move a large file across the Net.
Other ways to fill a 13 Gb hard drive include storing video files. These files require even more long term memory than do audio files. Currently, few people collect video files from the Internet because they are so memory intensive. Long- term memory requirements for video and audio files are driving consumer demand for larger hard drives on personal computers. As the cost of a hard drive continues to drop,users can be counted on to find new ways to use all of the long term memory on their computers.
In a culture in which you can never be too rich or too thin, you also can never have too much computer memory.
