You can use CopyFile WIN API #75 function. It seems to respect destination file name case.

>I have a unique problem. I have to transmit a file to a bank. Creating the file is not the problem. Transmitting the file is not a problem. The problem is with the case of the file name. The file name has to be upper case (bank is on a Unix system and is case sensitive). If the program is running on win2000 and I save a upper case file name it all works but if the OS is win NT 4 the file name is converted from upper case to lower case when it is saved. Does anyone know how I can over come this issue? TIA
