I had few databases related to different projects in the WAMP. I don\'t know what happened, Today, when I go to PhpMyAdmin, I was just able to see the default databases and rest
Copy data folder and reinstall same version of WAMP.
Once installation is completed, go to data folder: inside replace only ibdata1 file from existing folder.
After starting WAMP, check phpmyadmin: you'll get all database and tables with data.
