Thank you very much, this worked perfectly when run from a memory stick, but when I run it from the folder in which I have all my files, on our network share
I get the error
CMD.exe was started with the above path as the current directory. UNC paths are not supported. Defaulting to Windows directory.
Access is denied.
I guess this means I cant run this commend with a UNC path as the current directory? Access denied probably because us users don't have access rights to the c:\ drive.
However this shouldn't be a problem I can just copy the files to a external hard drive, do the rename then copy them back.
My friend you are a legend thank you very much for you help I really appreciate it.
