How can I tell what version of Delphi was used to create a project

If I开发者_运维问答 have complete source code to a delphi project, how can I tell what version (i.e. Delphi 5, Delphi 7, Delphi 2010 etc) was used to create it, without opening it in Delphi?

I have a number of projects dating back to Delphi 6 era that I would like to categorise. However I don't want to have to open each one in various versions of Delphi to figure out what version to use.

Delphi

project.dof

[FileVersion]
Version=7.0

BDS

project.dproj

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <ProjectVersion>
      12.0
    </ProjectVersion>
