Issues moving picture from phone memory to card memory.

I've had the LG Dare for a little over a month and I tried uploading pictures onto my computer today. I had taken quite a few pictures with the phone before I had gotten a Micro SD card, so to upload them, I tried to move the pictures from the phone memory to the card memory. Two of them moved but on the others a notice popped up that read "Cannot Rename" and a mix of numbers and letters. I tried doing it several times but neither time worked and I know there was a lot of available space on the card. Also, the same process worked with videos I had taken but not the pictures. What's the problem and how do I fix it?

Had a similar issue today. Couldn't get video files to transfer from phone back to card. Kept getting an error. Any help would be appreciated.

Try copying the media to the memory card, then delete the ones on the phone after the copy completes.

If it fails, then I would suggest formatting the memory card. Make sure to backup anything on it, because the format will wipe it clean.
