According to the information on the Internet, the chances to recover your hidden folders are very low. I recommend you to install Total Commander on your computer. After the installation go to Menu Bar > Configuration > Settings > Display > Show hidden files. This allows you see hidden files on your computer. Browse to the location where the folder was located and check its presence. If it's there, right click on it and copy its contents to another partition. However, there is a possibility that the folder is located in its original path, but cannot be accessed.
