What is a zip file?

Yes, it’s very basic. But I just got asked ‘what’s a zip file?’ (and you’d be surprised by how many people are afraid to ask that question) . A good answer can be found here. In summary

• Zip files allow you to compress large files into a smaller space (e.g. to make them easier to email)
• Zip files can allow you to group files together, so they don’t get lost.
• You can also password protect zip files for greater security.

Sounds impossible? A larger file squeezed into a smaller space, without losing anything. Don’t ask , it’s very clever and it just works!
