Windows File Compression

ZIP Files

Use Windows File Compression to reduce the size of a file. The benefit to you will be less space used on your hard drive or other media (CD, DVD, Flash Memory Drive) and faster emailing of attachments. The type of file will determine how much file compression will reduce its size. For example, digital photos (jpegs) are compressed anyway, so compressing one using this tool may not reduce its size. However, if you have a PowerPoint presentation with lots of images in it, file compression will most certainly reduce the file size — perhaps by 50 to 80 percent.

The Original File Is Compressed

Windows will compress the file or files into a zipped folder (Compressed folders appear as a folder with a zipper) and place it in the same folder as the original. You can see a screenshot of a compressed folder, next to the original one.

At this point, you can use the compressed file for whatever you want: storage, email, etc. The original file will not be altered by what you do to the compressed one – these are 2 separate files.
