[Correction]

I say this with absolutely no knowledge whatsoever of how the Graal client works or what it uses to manage files, but it might be worth noting that in some language environments on Linux a dot represents a wildcard. Whatever the issue is, it's definitely in the Graal client. It could also be something as simple as that the Linux client might split the filenames based on a period delimiter expecting only a name and an extension, or something like that.

It's all speculation at this point. What matters is that someone needs to fix this immediately because I am not satisfied!
