'Other' Storage is taking up too much space

My MacBook Pro 2017 has a 121gb hard drive in it, however 47gb is taken up by 'other' storage. I've looked at other questions on various forums and deduced that it must be my cached files, however, when coming to delete my expendable cached files, found that only around 8gb was removed from the 'other' storage, and the rest of the files only add up to 384mb, so removing them would barely put a dint in the storage issue.

My question is, what else could be taking up such a huge amount of storage, and what solution is there to resolving this?
