I was wondering if it ccleaner could have a "set compress attribute" option for particular folders and files that are little used but should not be removed. Perhaps setting the compress option about a set period of time e.g. 1 year since last accessed. An good example would be the XP service pack files that are normally kept in: C:\WINDOWS\ServicePackFiles. See techrepublic article for a discussion of this folder: http://articles.techrepublic.com.com/5100-...11-5816838.html I realise that this request goes the curent function of ccleaner (i.e. file deletion). It still fits in with ccleaner's overall purpose, or at least why I use it, namely to free up space of the hard drive.
