Actually, this tool has long existed in the laptop. However, I ignore because do not know the benefits. When there is a problem all the folders in a state of Read Only (can not be transferred and can not store files in it), I use it for fun because almost all of the antivirus does not detect the virus. Once cleaned using this tool, it turns out all back to normal folders. The files "junk"too, so the laptop can be cleaned more easily.
Apparently, despite using the free version, this tool is incredible benefits. Moreover, if we use the netbook. When it feels heavy, run this tool to completion, the netbook will feel lighter. If it is severe, there may be other causes. This tool is also useful to clean up all Internet browser cache, so that whenbefore the browser to remember your username and password, can be removed only with a single command.
How to use it?
Please download and install the application here http://www.piriform.com/ccleaner . Run the application and then click Analyze.
Wait until the process is complete.
When finished, click Run Cleaner.
If you're opening a browser, there is usually a command to close it. If not closed, the cleaning process on the browser's cache will be bypassed.
Once completed, there will be information on how big the file "junk" that had been cleaned.
If you've been using a laptop / netbook / computer, so its capacity can be cleaned very large files. Try it, because it is still free!
