So let me make sure I understand:

1. you want to edit what about a document? Filename? Content-type?  
If you want to edit the file itself, I’d think you’d have to download  
it, edit it, and then reupload it.

2. When you say from directory as well as database, do you mean that  
you want to be able to edit a file saved in the filesystem of the  
server and a file saved as binary data in the database?

Give us a littl’ more to work with so we can help…
