The has long been used to compress and archive data. Suppose you have, say, 50 Word documents that have a combined size of 5MB. By zipping them, you end up with a single file that's much smaller--maybe 1MB or even 500K. Imagine stuffing all your clothes into a tiny, lightweight suitcase--that's what compression does. Even better, when you open the suitcase, everything comes out wrinkle-free.
If you're already using a utility like PKZip or WinZip to compress and decompress files, there's little point in changing. But did you know Windows has Zip capabilities built right in? Here's how to use them on the fly, using the aforementioned e-mail as an example:
1. Compose your e-mail message, then click Attach File (or whatever is your mail client's equivalent).
2. Using the file selector that appears, find the files you want to attach. (They all need to be in the same folder.)
3. Select all the files you want to zip. (To select multiple files at a time, hold down the Ctrl key while clicking each one in turn.)
