<p>We are team of few Delphi developers who have been using VSS since years (I know it's a pity), but we don't use any of the advanced features of VCS, so it was working fine in many cases (but some times it was driving me crazy :( ).</p>

<p>The good thing that we have with  VSS that we use third-party plug-ins to integrate VSS with Delphi, which is working great, but now when our projects becomes larger, and we would like to move a way from VSS.</p>

<p>I have looked at few other VCS (free and commercial) and found most of them seems be made for Linux guys, and you have to use command line for many admin work(I know I'm windows guy :P).</p>

<p>What I'm looking for the new Version control that it should be easy to use and to maintain and Integrated nicely with Delphi IDE (D2007), or at least have a good UI for the Admins an developers.</p>

Just use
SVN
and an excellent
TortoiseSVN
client which integrates with the Windows Explorer.
P.S. Found this question:

and this Delphi IDE/TortoiseSVN integration tools in one of the answers:
