Could not locate file 'c:\Databases\mydb_1' for database 'mydb' in sys.database_files. The file either does not exist, or was dropped.

Hi,
I want to run the shrink command, but the sql query keeps giving this error.
I am using below command
DBCC SHRINKFILE('c:\Databases\mydb', 10) 
My databases are not stored inside the default sql data folders.

Thanks
...
