what are the possible causes of C drive getting completely full on Unity 5? How to troubleshoot?
Both the database files and the transaction logs are in the folder:
C:/Program Files\Microsoft SQL Server\MSSQL\data
So that is the folder in question.
Transaction logs end with .ldf
Database files end with .mdf
On the new partition, create a similar folder structure with the only difference being the drive letter.
Hope this helps.
