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.
I remedied this by creating a sub directory and putting everything in that directory and was able to copy all files just fine but it's just not possible to do so in the root. It got me thinking, is this why digital cameras always save their files to sub directories on the memory cards and not the root directory?
Any reason why the root would not allow all the files but a sub directory would?
