I'm using the code below to get all my custom file in my project,
Collection<VirtualFile> virtualFiles =
But there is a strange problem, this code only return part of the files in my project while I want all XXXXFile returned.
I created project in this way: On the IDEA welcome page, I choose Open Project, and select a directory which has sub-directories and XXX files.
What I missed if I want to get all XXXFile in this way?
