Welcome!
In Tools->Configure Paths you can Set a Path for Additional Libraries.
Say you set it to E:\B4XAdditionallibs\
then the best Structure would be
Create a Folder B4A in E:\B4XAdditionallibs\ and put there all B4A Libraries.
Create a Folder B4J in E:\B4XAdditionallibs\ and put there all B4J Libraries.
Create a Folder B4I in E:\B4XAdditionallibs\ and put there all B4i Libraries.
Create a Folder B4R in E:\B4XAdditionallibs\ and put there all B4R Libraries.
Create a Folder B4X in E:\B4XAdditionallibs\ and put there all
B4XLIB Libraries.
In this case you need to define the path E:\B4XAdditionallibs\ in all B4X Tools the same ;-)
