I created a database on a local SQL server that we use for development. I created the log and data files on a second hard drive (E:\MSSQL\DATA). I am using this database to do some speed tests so I created a lot of data (7 Million rows). I started running some pretty intensive queries and to get some test data I ran an update statement that updated all 7 million rows and now it has taken up all of the space on my C:\, which I don't understand since I put the data files on the E:\.

Is there some files on the C:\ that would be growing based on me running queries on this other database, if so how do I stop it? I am doing with this database but I need to get my C:\ back in order.

The database file group was PRIMARY, is this relevant?
