Delete .ndf file

Question

Hi

I used partitioning on my database. I created filegroup and four files in this filegroup. In this filegroup i dont have data and i need delete .ndf files from this filegroup. Files has 1MB size.

i used this command:

 

ALTER DATABASE MyDatabase REMOVE FILE MyFile

 

i got error :

Error 5042: The file 'MyFile' cannot be removed because it is not empty. 

 

I tried SHRINKFILE('logical_file_name', EMPTYFILE) but i got error:

There is insufficient space in the filegroup to complete the emptyfile operation. 

 

Do you have any idea how i solve this problem. Thanks
