Making Zip Files For Uploading
Mac OS X
Making ZIP Files (Compressed Files) in One Click on
To create a compressed file, either Control-click on the file and choose Create Archive (which is Apple-speak for “make a compressed ZIP file”). Or you can click on a file, then go to the Action menu (the button that looks like a gear up in the Finder window’s toolbar), and choose Create Archive from there. Either way, it quickly creates a new file, with the file extension “.zip.” This is the compressed file.
Zipping Multiple Files Into One Zip File
You can also compress several different files (like three, for example) into one single archive file — just Command-click (or Shift-click contiguous files) on all the files you want included, then choose Create Archive of X Items from the Action menu. A file will be created named “Archive.zip” (that’s it!).

Making ZIP Files (Compressed Files) in Windows
To create a .zip file, right-click a file, such as Government Proposal.doc, and then click a command on the shortcut menu, such as Add to Zip file or Add to Archive, to create Government Proposal.zip. Often the zip utility shortcut menu also includes a command such as Configure or Options to access the zip utility's option settings.
