Be sure to backup those things you can't lose. Moving sets off alarm bells because if there is any glitch during a move, the item being moved can be lost. That's why folk must copy it over then check their backups are OK before deleting their last copy.
Since DropBox is 2GB free and we have memory sticks, DVD media and more why is there no backup?
I have a Macbook (circa 2005) with approximately 23000 photos that I'm trying to move to external HD. Unfortunately, the external HD is unable to connect to the Macbook because it requires a more updated OS. And I can't seem to update the OS because there is not enough free memory on the Macbook. I have 2GB of RAM memory. The OS is 10.4. What are my options?
