I have plugged and shared my external hardisk with 2 computers in my network.
Both computers can read/wirte the files in the hardisk after mapped the network drive.

But when i copy the "photo" into the hardisk via the router, the photo filename will automatically changed to lowercase.
The most serious problem is that when i try to access the photo, it prompts me and say that the photo is opened by another program. I cannot view/delete/rename the photo now.

Please help......Thanks in advance.
