Hi all, i got a problem about overwriting a exist file now. the background is i open a file , then i do some conversion to the data of the file, after finish all conversion, i must overwrite the file .

Eg: the exist file path is
C:\Documents and Settings\USER\Desktop\EM017.D03 after i did the conversion job,
i have tried to save the file with the same path name, but the compiler always show error. i tried to save it using another name, it works. So can you give me some ideas? thanks a lot!!!
