Why can't I copy all files to the root of an SD card?

I have 4GB SD card that I want to put tons of small photos on for a digital photo frame but I cannot copy all the data into the root of the SD card. About half way though the copy it just fails and stops copying.

"Here's a KB article on the issue: http://support.microsoft.com/kb/120138.

There is a certain file limit on the root directory of FAT file systems, which SD cards typically use. This is why camera manufacturers store them in sub-directories, as you pointed out."
