Phantom files on my Creative Cloud Storage

[#1]

Hello,

I cleaned my Creative Cloud of all the files I had, yet I still have 222MB of phantom files. I'm unable to find the source of these 222MB, nothing on the "My Files" tab, nothing on the "Deleted" tab, nothing on the "Creative Cloud Files" folder on my PC... Is there anyway to locate these phantom  222MB ? Or to format my creative cloud ?

Thank you !

Clement.
