How can I change files from yaml format back to original format on Pycharm CE Follow Winnie Tongwanyee Created July 26, 2020 03:32 Hi! I accidentally changed the format of files from py/sql, etc. etc. to yaml. However, no matter what i do, I can't reverse the change (file still ends with its file type but format is all yaml) despite re-installing PyCharm. What should I do?
