Winapp2.ini additions in CCleaner Discussion Posted yesterday at 13:15 · Report reply 3 hours ago, siliconman01 said: Should these be added as ExcludeKey's to [Edge Internet Cache CC *] ??? I do not think so, because this is a special case only for this one extension. (The extension possibly does not comply with the specifications for Chrome extensions?) CCleaner's built-in entry has been removing these folders (HTML5 Storage) for a very long time now, without any issue reports.
