Skype ( on MacOS (10.10.5) keeps 600Mb in the two caches below, are these both deleteable without any negative effects? Can I prevent Skype doing this with any (Skype or MacOS) config setting? or do I just have to write a crude wrapper which monitors/purges these regularly? EDIT 1: wrt effect on performance, Skype keeps large disk caches, and crashes regularly, which may well lead to fragmentation.

348M    ~/Library/Caches/com.skype.skype/<username>/SKAvatarCache
213M    ~/Library/Application\ Support/Skype/<username>/media_messaging/emo_cache_v2

Related to the second: How do I prevent the Skype emoticon cache emo_cache_v2 directory from being populated with automatically downloaded images?

  • Questions get better answers if they are focused. In the current version of the question it's not clear whether you are asking about whether you can delete these two files, whether there is a way to prevent them from ever getting created, whether they are related to a (not explained) crash, whether they contribute to an (indescribed) disk fragmentation, or whether all of this this is part of a bigger problem (performance maybe) not even mentioned here. – nohillside Sep 3 '17 at 4:12

There's no need to delete these files, but there's no "harm" if you do.

  • The SKAvatarCache holds thumbnails of your contacts for quick access without downloading each and every time from the Internet

  • The media_messaging/emo_cache_v2 holds the animated emoticons for faster rendering.

You can delete, but these files will be recreated when you view and/or message with contacts. It's nothing that should be of concern that would require periodic maintenance.
