Add a property to nt:file?

[Joan Xiao <jx...@polivec.com>]

Hi,

 

I'm working with a document hierarchy structure - user is able to create
folders and upload files. When user uploads a file, I'd like to allow
user to enter a comment. I'm using the predefined note types such as
nt:file and nt:folder. How can I add an extra comment property to a file
node? Do I have to create my own node type? And if yes, how should I do
that?

 

Thanks a lot for your help.
