Selective recovery of files created by Pages on iPad

[hajime]

Hi, I backed up my iPad using iCloud and also to a PC via iTunes. Before that, I was working on a file under Pages. I did not change the filename so it is the default name decided by Pages. Is it possible to retrieve such file individually from the backup to another iPad?

If it’s on iCloud you should be able to visit the iCloud website and see your files online.

I logged into iCloud website as you suggested and found the file created by Pages. Thanks.
On my iPad, I had a few photos and about 10 videos. How come some videos are missing?
Hope the iTunes backup has those videos. Are we able to selectively access the files stored in iTunes?
It seems all the files are lumped into a backup file in a special format.

Before I got your reply, I installed the iCloud app to my Windows PC. After entering my ID and password, it shows 'iCloud Drive', 'Photos', 'Mail, Contact, Calendar Outlook', 'Internet Explorer', 'Book Mark', 'Password' all with a check mark. What are they for? I don't see any files nor folders.
