Can I erase opg data manually from Easydent V4 viewer?
The viewer will only let you access the data and view it without the option of modifying it. This operation can be done in the main software and luckily, there is an application for that.
Access the PDF file to see what are the allowed operations for EasyDent: http://www.ezdent.com/technote/EasyDentManual.pdf
Yes. you have to delete Root Folder from C drive and you can delete all OPG data manually.
