Including Files

Hey all, because VCS lacks autosaving and version history I have written most of my code in separate header files. The issues are that I have to define the entire address for the file. I have many different copies of my code and are consistently having to change the file address.
Ex. #include “/Users/1069B/2018-2019/Code-2019-Season/CompitionCode/FifthCompition/BaseTask.h”
Is there a way to shorten this address to something like #include “BaseTask.h”. The .vex file is in the same folder as the other files but whenever I try the latter code I get an error saying the file is not found.
Thanks for any help in advance,
