How to reduce this MDF file size ? what is unallocated space?

Is this database upgraded from SQL 2000 version?
What is the log file size?
Please run this query and post the results here:
use dbname
go
select name, type_desc, size/128 'Size(MB)', FILEPROPERTY(name, 'SpaceUsed') / 128 'SpaceUsed(MB)'
from sys.database_files
You can the reduce the MDF file size by using DBCC SHRINKFILE. But set the file size to appropriate size.
Unallocated space = 'Space in the database that has not been reserved for database objects.' (from BOL)

You can use DBCC SHRINKFILE. For example:
use IEDBNew
go
dbcc shrinkfile(IEDBNew_Data, 30720) -- 30GB

It is because there is used page at the end which needs to be moved to front of the file.
Please run DBCC SHRINKFILE with NOTRUNCATE option as shown in the following example:
use IEDBNew
go
dbcc shrinkfile(IEDBNew_Data, NOTRUNCATE);
go
dbcc shrinkfile(IEDBNew_Data, 30720) -- 30GB
go

Just remember that shrinking will cause the indexes to be fragmented. Therefore rebuilding the indexes will be required after shrinking has been done.
