My computer did the system, ali wangwang chat records are gone, how to recover ah?

If Ali Want Want was originally installed in the system's disk, then you reinstall the system, the original things are gone, can not be recovered. If AliWangWang installed in the non-system disk, then find the installation location of AliWangWang, such as: D: Program Files/AliWangWang, there is a folder profiles, which is the chat history.
