Disable Work Folders client free disk space check?

I have 3 TB Work Folder and I had todisable client side because of error.

Now I try to re-enable it, but I get "This location doesn't have enough free space. Choose a different location or clear 2,68 TB of space on this drive".

Client and Server sides have same files, so do I really need to delete all my client side files and resync everything?

Thanks!
