How can I open a file with an SPD file extension?
Hi
I have started a course for which I have received some literature in pdf format. I have made hand written annotations to a pdf file using my Samsung Note tablet, which I have then put into Dropbox, with the intention of storing on my IMAC.
I then tried to open this file on my IMAC but received a message that Adobe Reader couldn't open it as the file was not supported, or might have been damaged.
Any ideas on how I might be able to get around this problem?
Do I need something other than "Reader"?
Comments will be very gratefully received by this novice user
regards
