Hi All,
In my drive E:\ I'll have a space issue soon because one file is taking all space. SYSTEM01.DBF size is around 25GB. I want to know if I delete some data in my database I'll gain space. If there is also another solution please tell me.
Regards.

Yep. One of the ways to make datafiles smaller again after deleting data is for example creating a new tablespace with new datafiles, move the object to that new tablespace and then delete the old tablespace and datafiles.
Of course that (and probably most other) techniques to free up disk space won't work if the objects are in the system tablespace.
The only option I can think of would be to create a completely new database with a correct tablespace layout, and then export/import the data into a correct user tablespace.
