How to access to a file, which is on a "ghost" X:/ LIBRARY/ path ?

Hey,

I downloaded a vector field packs, which works with .FGA vector fields files.
In Unreal engine I access to .uasset files, and these assets sources are on a strange path like " X:/LIBRARY/…".

I don’t have an X drive on my computer, I can’t find them and I would like to use these sources files in an other software … Is there a way to get them ?

Thanks !
Quentin
