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.
*Windows Explorer* prevents you from creating a folder or file
whose name STARTS with spaces. It trims them automatically,
whether you want it or not.
So it's NOT a surprise that *Windows Explorer* (!) has problems
if you use it on such files which were created manually.
But obviously, *Windows* OS doesn't prevent you to create them
through scripts and applications...
