Define color by filetype bug.

[dexus]

Directories with a name with a dot inside are highlighted as files.
[testfolder.zip] will be the same colour as a zip file would be.

Surely this is not supposed to happen for directories.

You may additionally define the attribute directory as false.

Indeed this isn't a bug, TC simply matches the filter to the name. You can use the "Define" button to define a custom type where attribute - directory is unchecked, and the others are grayed.
