i have recovered the deleted picture with the help of recuva but i am not able to open unrecoverable picture is there any way to restore such file
Recuva will restore what it can, but if a photo comes back that has been chewed up by being partially overwritten then some image viewers will simply report it as corrupted and refuse to attempt to open it. Some success has been reported in the past from trying more fault-tolerant viewers such as IrfanView https://support.piriform.com/hc/en-us/articles/209176787-How-can-I-recover-photos-
