*.xcarchive and similar are just normal folders if I look at them with command-line tools (
ls, etc.). Still Finder treats them different from normal directories, e.g. double click opens
*.xcarchives with Xcode archive content viewer.
Is it somehow possible, to make Finder behave so that such folders aren't treated specially compared to any "normal" folder? Alternatively, if that is not possible, is there a file explorer, that "ignores" file extensions and just treats every file with "d"-flag as simple directory (I tried a few, but they all seem to behave like Finder)?
