If you're working in Pages 5.5 or later, Numbers 3.5 or later, or Keynote 6.5 or later and have created a file that is larger than 500 MB, saving it as a package helps the app you're using perform better. By default, these versions of Pages, Numbers and Keynote auto-save files to the hard drive as a single file.
If you experience app performance issues and you aren’t planning to send or store the document using a third-party (non-iCloud) Internet service, then save as package. Otherwise, it's best to save as a single file.
Save as a package or a single file
If your document, spreadsheet or presentation is 500 MB or larger, you might see a message that reads:
- Pages 5.5 or later: "Would you like to save this document as a package?”
- Numbers 3.5 or later: "Would you like to save this spreadsheet as a package?”
- Keynote 6.5 or later: "Would you like to save this presentation as a package?”
Choose Keep Single File if:
- You plan to send your iWork for Mac document to an non-iCloud Internet service such as iTunes U, Dropbox, Gmail, or another site where you upload files through your web browser.
Choose Use Package if:
- You're saving your document to your hard drive.
You're experiencing spinners or slow performance when editing your document.
You plan to send your document to someone using Pages for Mac 5.2–5.2.2, Numbers for Mac 3.2–3.2.2, Keynote for Mac 6.2–6.2.2, or iWork for iOS 2.2–2.4.2.
You can switch between a single file and a package at any time. Open your file. Then choose File > Advanced > Change File Type and select the type you'd like to use.
