ricky writes "One database called P42. SQL administrators decided to add datafiles as they think is needed as oppose to letting one datafile grow unrestrictedly in the last 2 years. I picked up the support for the server recently and been tasked to consolidate all 10 datafiles for this database P42 about 150G. I am in need of the proper process on how to do this. Please help. Thank you."

The previous Administrator probably choose that route because Multiple Datafiles (Filegroups) help with balancing data load across multiple disks and they use parallel threads to improve data access which boils down to improved performance.
But on the other hand too many filegroupgs can cause too many parallel threads can cause bottlenecks
