I hate to ask the same question in multiple places, and I asked for the same question at the Skype community forum, but the answer at that forum just suggested that, unfortunately, there is no way to disable the feature I wouldn't like to use. So probably I'm looking for an alternative way.
Recently I've found that my Skype application profile directory is quite big. Analyzing the directory structure of my Skype profile discovered an usually big size of
%USER_PROFILE%/AppData/Roaming/Skype/.../media_messaging/emo_cache_v3 -- about 128MB. The directory contains really a lot of image files (about 4.5K), and I don't see why do I need them to be deleted knowing that I have never used any of them. Ok, I've moved JPEG, PNG, and the _distr files out of that directory to make a cleanup. Once I click the smileys button the in the chat window, I get some now images downloaded again. No... I don't want to use enhanced emoticons ever, and don't want my profile directory to be stuffed with such images. Well, I really can't see any particular reason of why I might be interested to use them.
Is there any way to disable the enhanced emoticons and stop them to be downloaded forever? However, I would like to keep all standard yellow smileys. The only way I'm thinking at the moment is a scheduled job to make a sort of cleanup right there, but I cannot see how to identify and not to delete "not standard yellow" smileys.
