As a!deleteDocument can only delete a single document, you will need to create a process to delete multiple documents.
Documents in Appian are referenced by their ID either in a variable of type Integer or of type Document.
how to get folderId? why each time refresh the interface the folderId return differently?

I can neither see your screen, nor your code, nor do I know what you want to achieve, what you tried, what failed or anything that enables me to give you an answer.
I tried to explain this to you already a few times. It is that simple: No details -> No answer!
Do you know how to let the folder's existed files already shows up once come to the fileupload interface? The previous problems solved.
