After finally figuring out how to run a downloaded .swf file in a private browsing mode (first time I've touched internet explorer on this computer) I've started a full run of CoC. Due to the mentioned private browsing, the best/ only way for me to save my progress is through the file format. However, the downloads do not save as any particular file type, and as a result won't load when opened with "load from file". What file type do I need to slap onto the end in order for it to work?
