Glen Taylor just released a plug-in for WinMerge that makes it easier to compare Visual FoxPro’s VCX, SCX ,FRX and LBX files.
This is “for those who are not using the Source Control integration in VFP where you put the project into Source Control and VFP uses SCCTEXT to build the VCA, SCA and etc files.”
Definitely interested in that!
Any chance you have an archive copy of the plugin? All of gtaylor's links to it point to 404s or errors.
