What happens to the files created by user, whose account is deleted.

Hello,

I created a folder in the My folders names "Quote"
I shared the same with my colleague.
She created some files and folders in that folder over the period of 1 and half year.

Now she left company, and I deleted her account from Zoho.
What happens to the files and folders created by her. 
Whether they are also deleted or retained.

Thanks, and regards,
