Primary filegroup is full SQL Server 2008

Follow these steps:

1. Identify how much space you want to add to the database storage allocation:
   1. Open windows explorer
   2. Right click on the disk drive that your database files exist on
   3. Select properties
   4. Check how much disk space is available and decide how much of this you want to allocate for the database
      (Suggestion: Leave at least 20% disk space free if you house the database files on the same disk as your OS {Sub-Suggestion: Don't do this! Rebuild/migrate your data to it's own disk; you're screwing yourself on I/O.} and leave at least 8% for a pure data disk; these numbers are estimates of what I think the actual percentage suggestions are.)
2. Update the storage allocation for the database.
   1. Open SSMS
   2. Click the "View" tab
   3. Select "Object Explorer"
   4. Expand the "Databases" folder
   5. Right click the database your trying to bulk insert into
   6. Select "Properties"
   7. Click the "Files" list option from the "Select a page" area at the left of the properties window
   8. Find the "Database files" row with the "Filegroup" as "PRIMARY"
   9. Add whatever number of megabytes you want to add to the database allocation to the "Initial Size (MB)" number
   10. Hit "OK"
       (You might also want to consider your "Autogrowth" values while you're here.)

You want to give your database as much storage allocation as you can afford to give it. If it runs out of space you'll receive this error without auto-grow on and if auto-grow is on you'll take a performance hit each time it has to auto-grow. If you are simply out of disk space then that is your answer and you need a bigger disk.

Express Edition 2014 has a limit of 10 GB per database. If the auto grow of a database hits that point SQL Server throws the (obscure?) error message, not mentioning license limit. There may be plenty of disk space but you still see this message.

Remedy if design allows for: use multiple databases under this license.
