in reply to Re^2: rename file
in thread rename file

Thank you for clarifying this point, I almost mentioned NFS. OP didn't seem quite ready for a lesson of file systems, but I did want to relate it to what might actually be happening since they were thinking the operations were extension or file type aware. I also assumed they were coming from a more vulgar environment, like Windows (but used unix commands to illustrate the point nonetheless). That and using old skool CGI from 1990 seem to go hand in glove
