Drop Datafile and Reuse the Tablespace – Oracle

Oracle 12C is my database. I was moving the datafile from one directory to another directory by making the tablespace Offline.

ALTER TABLESPACE TABLESPACE_NAME OFFLINE NORMAL;

But accidently, while moving i haven’t changed the tablespace to offline for one datafile.

When i am trying to bring back the Tablespace Online, it giving the error as,

Error report:
SQL Error: ORA-01113: file 161 needs media recovery
ORA-01110: data file 161: 'K:TestTEST01.DBF'
01113. 00000 -  "file %s needs media recovery"
*Cause:    An attempt was made to online or open a database with a file that
   is in need of media recovery.
*Action:   First apply media recovery to the file.

Whether its possible to drop that datafile alone, and make the Tablespace Online.? Since i am lot of data in that tablespace, i cant able to drop that tablespace.

Note : I am having only one table in the entire tablespace.
