All your chat history is saved in one file – main.db. You will find this data base file in your Skype user folder.
Go to Windows Start and in the Search/Run box type %appdata%\skype and press Enter or OK button. In the File Explorer window, that will pop-up, locate a folder with your Skype user name. Find there a file with the name "main.db". You may see only “main”, but the description will say Data base file.
