What is image decompression?

How does Windows decompress files automatically?

When a compressed file is opened, Windows decompresses it for you automatically. When it closes, it gets compressed again. This happens over and over as many times as you open and close a compressed file. We turned on the compression attribute for a 25 MB TXT file to test the effectiveness of the algorithm Windows used.
