Possible CCleaner Improvement ?

Hi

I'm new here so please forgive me if this is the inappropriate place to write what I'm about to say :)

I upgraded to widows 8 a while ago and with days passing I noticed a very notable decrease in C: free disk space

literally tens of megabytes were getting lost day after day even though I clean my C: drive with Ccleaner regularly ..

First I started using programs like TreeSize and TuneUP to figure out where the space is getting leaked into but other than my personal chuck of known files there was nothing too big taking space ..

so I started freaking out because soon I won't have enough space to store my own stuff and I still don't know who's robbing my megabytes xD

I did some random file searching on different locations to finally discover that there's about 1 gigabyte of Cached files located in the Appdata folder just sitting there ..

and no matter how many times I run Ccleaner or what options I tick the files don't go away ..

most of the files were JPGs and PNGs but what really angered me is that there were stored mp4 files of half completed youtube videos

there was also some .txt, XML and some unknown files,

location is "AppData/Local/Packages/"app name"/AC/INetCache"

the INetCache folder exists in any windows 8 app folders, and you need to Untick the "Hide Protected operating system files" in folder options ..

My question is how OK is it to delete these files ? .. and if it's ok then would CCleaner add the option to handle this kind of folders appropriately in the future ?

Have a look at http://forum.piriform.com/index.php?showtopic=37192 and http://forum.piriform.com/index.php?showtopic=32310&st=2660 (post 2669).

There's quite a lot in Google on this, but I can't find or give a definitive yes it's safe.

ok, thank you

The latest winapp2.ini has baked in support for several windows 8 applications.

If you find that you've got clutter in places not covered by winapp2.ini, please, do let me know the paths (preferably on the winapp2.ini thread linked above, but here is fine as well) so I can add them in.
