does this mean video sent in message???

[katkitty73]

Hi could anyone tell me what this path means sd/sd0/messaging /shared. A video was in gallery folder under the shared folder when i clicked on details this was the path. I don't remember messaging or sharing it. Is there a way to find out if and where to it was messaged/shared? The phone is a Motorola xt910. Any help would be greatly appreciated.
