Delete file

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

Hello,

Can someone please show me how do I prevent user from deleting file ?  I created a folder call "Draft" so the user can upload files but I don't want the user to be able to delete the file once they upload it (Only admin can delete file). 

Thank you

Hi,

Here is a sample permissionDefinitions.xml. Basically you need to define custom role  and set that role to the users/group to the folder draft.
