In particular, I created a project, with the mmp file in \private\svdwal\prj\prj_s60\prj_s60\group. That is one prj_s60 too many, so I deleted the project in Carbide, removed one of the prj-s60 folders and reimported the project as a project (not the bld.inf or the mmp file)
Now compiling the c++ source files goes fine, but compiling the .aif, the _*caption.rss and the *.rss file all go wring. In particular, Carbide still thinks these files are in prj_s60\prj_s60, instead of prj_s60. I can open the files themselves just fine in the editor, but the resource compilers still think these files are in the old position.
