ExtractRelativePath seems to work well, thanks.

Now, damn, it seems that FileUtil.CreateRelativePath works correctly, too.
I was testing it in Lazarus Converter code and it used a version in 
lazarus/ide/ideprogs/ instead of FileUtil, even though FileUtil is higher in 
"uses" list.
I think there is some redundant and useless code in Lazarus, but it is 
understandable in such a big project.

So, these 2 work identically in my tests and you should be able to use them, 
too:

    RelPath:=FileUtil.CreateRelativePath(PasFile, ABasePath);
    RelPath:=ExtractRelativePath(ABasePath, PasFile);
