Kirk,
I am having an issue renaming a folder of files. At first I thought that it might be an OS thing but having returned to the office I just moved the files form the laptop and am having the same thing here.
I have a folder of images shot with a D3(Nikon) Images were ingested by PM and are jpg+NEF. They open and look fine. No corruption in the files themselves. I moved the fist offending file and tried the rename again but had the program report the error again on a different file.
The error just reads "An error occurred while renaming photo 8-25-2008-0498.jpg. The operation will be canceled and the original names will be restored"
I also ended up with a 1/2 folder of files named _###_TMP_numbers_
System one was a laptop running Vista 2gb Dual core. System two is XP Pro on a Pentium 4 with 3b.
