Zip Files

Zipping files are a way of archiving and compressing your data. A ZIP file contains one or more files that have been compressed to reduce file size. Think of a very well packed suitcase, it’s much more efficient and smaller than a heap of clothes.

The main reasons to ZIP a file are:

  • Emailing large files
  • Emailing multiple files
  • Emailing files you can’t normally email (such as .exe files)
  • Encrypting files to protect sensitive data
  • Saving space on your hard drive

Current versions of Windows and Mac both allow zipping and unzipping of files.
