Opening a .pages file, which is a document created by Apple's Pages app, can be tricky if you don't have a Mac. One option is to use iCloud by uploading the file to your iCloud account and accessing it through their web-based Pages app. Another way is to change the file extension to .zip and extract it to access the content. Have you tried opening it on an Apple device, or do you mainly use Windows? Feel free to share any specifics, and we can explore other solutions together.
