Today i've checked roaming folder of cyberlink. I find a surpise that it contains thumbnail cache, waveforms cache of my all files which i've edited on power director in past

I don't understand why does power director save this cache for so long?

Like there is automatic option of deleting shadow files after 1 or 2 days but where is option of deleting cache files.

There are many cache files which i don't understand like splitterindex etc. What is the use of splitterindex?could anyone explain the use of all cache in power director.

This is stupidity that everytime one need to open roaming folder to delete cache files. Does anyone knows any software which delete all cache of power director. I've checked some software. Ccleaner doesn't support cleaning of power director. Glary utilities only cleans mediacache files.
