is it ok to delete the random adobe files on my macbook?

hi i had adobe reader on my comp but i realized i didn't need it so i deleted the main icon in my apps folder. however, when i searched adobe in finder i found all these other folders titled "Adobe" "Adobe Utilites" "Adobe PCD" and "Adobe Custom Dictionary" and a few others.

i mean reader was the only adobe program on my comp so can i delete them or do other programs use adobe files?
