One point of view is that the expected behavior is that the

not allow programs to create files and directories with invalid
paths. Consider, e.g. that a user writes a program that creates
a large tree of deeply nested filesystem objects. When they are
done and wish to delete them, their file manager fails and
displays an error. The user's conclusion? D sucks because it
corrupts the filesystem and creates objects they can't operate
with.
You don't even need to use crazy third-party software.
Try this program:
mkdir(`\\?\C:\ a \`);
write(`\\?\C:\ a \a.txt`, "Hello");
Then, try doing the following:
- Double-click the created text file.
- Try deleting the directory from Explorer (by sending it to the
recycle bin).
- Try permanently deleting it (Shift+Delete).
- Try renaming it.
All of these fail for me. Deleting the directory doesn't even
show an error - nothing at all happens.
When the OS itself fails to properly deal with such files, I
don't think D has any business in *facilitating* their creation
by default.
