Windows includes the tools needed to uncompress files that you (or prior versions of Windows) might have compressed using Windows File Compression.
Since the dawn of the digital age the argument has raged: which is better – digital or analog? CDs or vinyl? I touch on some of the issues, but the bottom line is that if you can’t hear the difference, which is more convenient?
Windows File Compression automatically compresses files so they take up less space. In the best of circumstances, it can free up a lot of space, but all too frequently it’s not as much as you might expect, and there is a cost.
Most music, picture, and movie files are already compressed. The result is that compressing them again won’t make much difference and could even make them larger.
