Can’t open or rename file (name is too long)? SMH

There’s no context menu for rename, I’ve also tried clicking on it when it’s highlightd (which usually changes name too). It wont open in realplayer VLC or WMP.

I get this error “The file name is too long.” when trying to open it.

I’ve also tried to convert it but thje converter software says unknown file type.

Any help much appreciated!
