The online sources told me it is in a main.db file under my Skype username under the user folder. However, for the windowsapp win10 version of Skype, I cannot find either a folder named after my skypenmae, or a file called "main.db" in my entire drive.
Are there anything I did wrong?
Someone suggested that the chat history is now fully online, which is not true because I can still view my full skype chat history when offline.
Update:
There is neither main.db nor skype.db in my folder. There is a "database.db" under the "\AppData\Local\Packages\Microsoft.SkypeApp_kzf8qxf38zg5c\LocalCache\Roaming\Microsoft\Skype for Store\databases". The "LocalState" folder is empty in my case.
