If you want to change the version information in a .res (resource) file of your Delphi (win32) or C++ Builder project, but you don't want the hassle of compiling .rc files. Or you just want to do it in a batch file: use the easy way, use ChangeRes.Simply do on a command prompt or in a batch file:aChangeRes Project.res [VERSIONINFO] FileVersion=1.2.3.4And the FileVersion of your Project.res is updated. And if you are building Delphi or C++Builder executables it can update the options file (.dof, .bdsproj or .bpk) for you too. Not only the FileVersion can be updated but other version properties also.
