Folder is recognize as a file, so I wonder what is ContentType.Other actually mean in this case. I've thought that folder is detected as ContentType.Other

Both files and folders fall collectively under file systems, in this case the Windows File System (WFS), and logically therefore fall under the same enumeration as ContentTypes.Files. Folders are simply put a collection or grouping of separate files in a system. ContentTypes.Other targets data types that are complex in nature or contain special formatting information (e.g. email attachments) which would ideally not be recognized by most applications.

Hope this helps.
