A couple of places I would start would be:
- A new, community-hosted Unreal Engine Wiki - Announcements and Releases - Unreal Engine Forums,Read%26_Write_Any_Data_to_Compressed_Binary_Files
- (39) Rama's Extra Blueprint Nodes for You as a Plugin, No C++ Required! - Blueprint Visual Scripting - Unreal Engine Forums!
And if those don’t meet your needs, you could always try contacting Rama directly via a PM: https://forums.unrealengine.com/member.php?552-Rama
