Best way to do a backup file

Hello

Before processing a file I want to do a backup of it.
I think about copyfiles

copyfiles myfile myfile.bak

It is the best way ?

Thanks a lot

i'd add an iffileexist dialog and a messagebox which would ask the user, if he wants to overwrite a previous backup file.

Hello Yathosho and thanks with reply

But how do you do the backup of the file before processing?

Thanks

CopyFiles?

CreateDirectory "$INSTDIR\Backup"



SetOutPath $INSTDIR



IfFileExists "$INSTDIR\file.ext" 0 +2

CopyFiles "$INSTDIR\file.ext" "$INSTDIR\Backup\file.ext"



File "file.ext"

File "..."



RMDir "$INSTDIR\Backup" ; remove backup dir if empty

-Stu

Thanks
