At Present we can only delete sent messages at local level. But the recipient of the message still seeing that message. If you send some message by mistake which can be regrettable, you can edit or delete that message before the recipient sees that like skype. WhatsApp is testing another feature on its iPhone beta app that lets users preview the contents of archive files – such as ZIP or RAR – shared with them. The feature was once again tipped by @WABetaInfo.
