Why is that necessary?

You have options here. First, just iterate on all the document and sum it up.

sum(
  a!foreach(
    items: folder(<YOUR_FOLDER>, "documentChildren"),
    expression: document(fv!item, "size")
  )
)

Or, store some meta data to the database and do that aggregation over there.

But even more important, check out the excellent documentation

As part of the application I'm working on, I want to display the how much disk space is used by all the documents present in the KC of the application.

If it is one application I can use call document(<YOUR_DOCUMENT>, "size").

You cannot use any Java in normal Appian. You can write plugins in Java.

Why do you need Java to display the size of a document? Just call document(<YOUR_DOCUMENT>, "size").
