SOLVED: How to ".pages" extension in Windows

".pages" is, i think, the extension of word app of mac. Similar to ".doc" in windows. Interestingly, Microsoft word is unable to open file with ".pages" extension, but there are two methods to open this tricky file.

1. Just change the extension name from ".pages" to ".doc" by rename the file. But in my case, this method didn't work.
2. Open a file with ".pages" extension in icloud by uploading the file to icloud and open it online, and then save the file with the extension you want. Mostly, icloud offers you couple of choices of extension such as pdf, doc, xls, etc,. In my case, this method perfectly worked.
