Hi, I have over many files sitting in a videocam, overtime not all files have been backed up, and what was backedup (50%) is in seperate folders (eg, by events) mounted from NAS (synology) What I need to do is find the files that have not been backedup, review them and backup (selectively), and finally I hope to confidently clean my videocam completely. I have been trying to find a tool to list all files in my sony, thats not present in the organized folders. I would like to see the results in a finder like app so I can review the videos before I copy them over or just delete unwanted vids. Addnly, terminal command will also be useful to make final repeated checks that to be sure nothing is missed out.... Please help. h/w: mac air (recently switched from windows) Thanks.
