When trying to use the command-line command “cd” to change the current directory, Total Commander does not trim leading spaces in the path, which means if there is more than exactly one space between “cd” and the path, the command fails and does nothing. Cf. the behavior of CMD.EXE, where all surrounding whitespace is ignored.
Thanks for info. Even though all the resolutions/replies are wrong, as this _is_ a bug, at least I know now. And, the feature of allowing “cd[space][space]"path"” is better than nothing, I guess.
