@ni_c - here's what I'd do (indirect answer)
I assume you're wanting to put the links into the Comments column or a Long Text custom column
Drag the file from my file manager to the comments editor (Normal View), that will create the HTML. Adjust the descriptor in the HTML View (probably to just the file name), make it pretty (Bold, Italics whatever) back in Normal View.
I'd use a custom column rather than Comments - a) because I might want to download Comments which would clobber the link, and b) because I can edit a long text custom column (in a 'dedicated editor') from the Book List by using F2 on the cell.
Need to add the custom column to Book Details in Preferences->Look and Feel.
I also cloak long text columns with column icons, I make the icon conditional on the column not being empty.
