How to compress files and folders

To create a zip file on a Windows computer:

• Locate the file(s) or folder you want to compress. If you select a folder, all the files in the folder will be compressed.
  

• Right-click on the file (or multiple-selected files) or folder you want to compress, scroll down and select Send To, you should then see the Compressed (zipped) Folder option.

• To select a consecutive group of files or folders, click the first item, hold down the SHIFT key, and then click the last item.

• To select a consecutive group of files or folders without using the keyboard, drag the mouse pointer to create a selection around the outside of all the items you want to include.

• To select non-consecutive files or folders, hold down CTRL, and then click each item you want to select.

• This will create a zip/compressed version of the file(s) or folder(s) in the same folder.

• Original files or folders will not be changed.

• You may now send the zip file.

To compress (archive) files or folders in Mac OS:

• Control-click or right-click on the file or folder (or multiple- selected files or folders) to be compressed (zipped).

• On the pop-up menu, click Create Archive of "file name" (or Compress "file name" depending on your Mac OS version).

• A zip-format compressed archive of the selected files or folders will be created on the desktop.

• Original files or folders will not be changed.

• You may now send the zip file.
