Create tablespace "error in creating database file, access denied (OS 5)" I try to create a database file in this location 

I've checked the route and everything, I've tried several times to create the tablespace like this...



...but as you can see, I was just lead to several errors. What can I do? What am I doing wrong?
Do you have permission on this directory?
Under which user are you running SQL*PLUS? Administrator? – 
if no than got permission first 

if yes 

CREATE TABLESPACE lmtbsb DATAFILE 'file_path/lmtbsb01.dbf' SIZE 50M
    EXTENT MANAGEMENT LOCAL AUTOALLOCATE;
