What does compressing files actually do?
File compression is a data compression method in which the logical size of a file is reduced to save disk space for easier and faster transmission over a network or the Internet. It enables the creation of a version of one or more files with the same data at a size substantially smaller than the original file.
How much can text files be compressed?
Certain data files, such as text files, picture files in the BMP format, and some text style database files can often be compressed by 90% or more. There are some other types of files, such as program files, that may compress by 50% or so.

Text compression algorithms aim at statistical reductions in the volume of data. One commonly used compression algorithm is Huffman coding [Huf52], which makes use of information on the frequency of characters to assign variable-length codes to characters.
