I have been sent an email with a .JP2 file attachment that I am unable to open on my Windows 7 desktop PC. When I checked in Control Panel > Default Programs > Associate a File Type with a Program, the JP2 file type has "Unknown Application" alongside the entry.
Does anyone know how to open this type of file ?
I have looked on the internet and found a number of sites offering free software downloads but from comments made not all work successfully. Some comments caution the Installers are not clean. Consequently I am reluctant to download and install anything as I don't know which ones are free of malware etc.
Any advice would be really appreciated.
