How to view iCloud files in iPad.

Hello Everyone Reading This,

How do I view the individual files located in iCloud.com from my iPad Air, so, I can delete some of them and free up some space?   Please, be specific for each step from start to finish.  I cannot backed up my files because I do not have enough storage and says I must purchase more storage space before I can backup my iPad.

I do not want to purchase more storage space on icloud.com.  I would rather be able to look at my files and decide if there are some taking up unnecessary space and make room that way.

Also,  perhaps, someone knows of a way to quickly check for duplicate files or pictures that could be deleted.

Please, be specific in your answer… each page, section on page, word I am looking for, lol, you get the picture, don’t leave anything out.

I want to thank everyone in advance for your assistance with helping out in this situation.

Have a fantastic day!
