Not a direct solution but there is a japanese lib called JDokan (well, it's a Java wrapper over Dokan) which allow you to write file system extensions (in the same way Fuse allow you on Linux). As a Java developper, I guess it could be possible to write an implementation using OpenCMIS client lib to connect to server ...
I did not find such a tool so I wrote this one:
./clear-cmis-folder.sh /the/folder http://the/cmis/url theuser thepassword
It removes all documents and folders under that path.

Tested on Alfresco.
For production use, I'm not aware of anything. Generally speaking, a filesystem wouldn't offer enough functionality natively for a fully complete and production ready CMIS Server.
However... You've clarified in the comments that this is for personal / demo use, so you're in luck! Apache Chemistry currently ships two different example/demo CMIS Servers, ...
I implemented @Riduidel's idea, and called it Aegif CmisDrive. I made it open source.
As the screenshot above shows, you can mount any CMIS repository as a drive. I tested it with NemakiWare and Alfresco.
Not everything works, but it is sufficient for my immediate needs. Anyone feel free to propose better software if available.
I haven't worked with Alfresco in a long time (too complicated). Seems the development and community have come a long way since 2010.
What's wrong with Alfresco's own stuff, or an add-in? I was able to find the Repository Size Dashlet: https://addons.alfresco.com/addons/repository-size-dashlet does that meet your needs?
FlexNet is a .Net project on Github which has a server-side CMIS implementation:

I don't know any software that do it directly, however, perhaps you can find it has an ESB (Enterprise Service Bus) module out as a Service Gateway.
If you do not find one, you can assemble it. It should be easy if you assemble has an ESB module.
An ESB is a software that allow to connect different or same services under the same bus. So you can expose the ...
