The media and folder structure is IContent. If you go into admin mode and set access rights you can navigate the strucutre to get the id of your folder.
I did a small tool last year for copying blocks from a folder wich might give you some help on the way. Im not sure wich version of EPi that I used so accessing folders and loading blocks might have changed.
I am using the latest version of episerver through nuget package ii.e. 184.108.40.206.
I have a requirement to access folder structure which contains shared blocks and each block has content area which contains nested block and are of type CategoryBlock. A
My folder under Block asset pane are
Navigation Folder -> has one navigation block which has a content area, and each content area, has nested blocks.
Question is to pick the Navigation Block from Navigation folder, Can I access the that directly rather than dragging this shared block to any page.
Basically I would like to access the block using the Folder structure i.e. Navigation Folder.
Can you suggest a code snippet please?
Hope i have explained it well.
