Disk usage warning form WHM server

In this case we need to find out the storage where we have been spend lot data

#df -h   //will describe the disk usage details
.
.
mainly some .trash will get more data, so let look about .trash

#cd /home/user
#ls
.
.
// here hidden files not showing
#ls -a
.
.
//here have been showing all files

#du -ch /home/user/.trash/
...
.
//in my server it was around 12 gb

then I've used to remove them

#rm -rf /home/user/.trash/*   // it will delete all files form the .trash folder

#df -h
.
.
// now i got huge space.
