Clearing some of the Back-Ups on my Passport

I have a WD Passport which is 500gb,

however currently as i’ve had to reinstall the software it is saying there is not enough room to back up as there is 400gb of back up data already on the drive (the rest is my own documents that i dont want to delete)

how can i clear some of this 400gb’s? i do want to keep the most recent back up but the rest can be deleted if only i knew how!

Hi, you can easily explore the passport manually and delete (right click delete) the files that you don’t need.
