SLDLFP

This question has probably been asked before, so I appologize if it has and I could not find the answer.

When I send my native SW part, assembly and drawing files to collaborators where custom profiles saved as sldlfp have been used (as with wledments) must I send the sldlfp files along. If so, where do they put them and will the program automatically find them? Any additional insight into this would be helpful - in case I am not asking the right questions.

Currently I have a file folder here along with the required sub folders: C:\SolidWorks Custom Profiles
