well, obviously you loose the data stored in concerned tablespace via tables. You need to do it gracefully ,within oracle.
Directly deleting the files in OS, would be disastrous.
Question is Why? Why are you deleting the datafile?
Before doing anything, consult the documentation

It would be better to delete the data from within Oracle and then resize the datafiles to retrieve unused space.

Deleting datafiles just because they occupy space is never a good idea. Datafiles are meant to hold data.

What you should be looking at is
1) What kind of data does the tablespace which has this 30G file hold and how cruicial it is to the org?
2) Can you archive some of the data or delete some data off of this tablespace?
3)Do you have sufficient space on the server to do some re-org?

Try these first and then decide with the proper permissions to delete the datafile!!
