How to clean Liferay files and server diskspace

Question

I am working on Liferay system, where I uploaded almost 400 GB data. Because of some unavoidable reason, I deleted all the files from Liferay.
But when I check at disk, I can still see disk is occupying almost same data what I uploaded.

As I cant delete the files from document library, Can anybody please suggest how to clean my disk?
I want to upload that data again.

Answer 1

Temporary folders/files that can be removed:

• /LIFERAY/data/lucene
• /LIFERAY/data/jackrabbit
• /LIFERAY/data/osgi
• /LIFERAY/logs/ (all files)
• /LIFERAY/TOMCAT/temp
• /LIFERAY/TOMCAT/work
• /LIFERAY/TOMCAT/logs/ (all files)
