Pictures are the worst for backing up, actually no backing up someone else's pictures is worse.

Parents for example, my mom takes a lot of pictures she wants to keep I take lots of pictures I don't care about.

Semi-wheneverly when I manage to get the card from the parent's camera or cellphone to back up it's usually a mess of I backed up 63% of these so which ones are new. Is IMG0003.JPG the same as IMG0003.JPG I saved already wait no one is 2MB and the other is 3.25MB.

Meld helps but it's the same thing what do I have and what is new and what is different with the same name but is different which I just happen to notice due to the file size.

So I end up dumping it all onto something or multiple somethings and swear I'll figure it out next time. Goto step 1.
