Common abstraction layer for `IFileInfo`, `IDirectoryInfo` and `IDriveInfo`?

[Rekkonnect]

IFileInfo and IDirectoryInfo are both under the IFileSystemInfo interface, but IDriveInfo is only under IFileSystemEntity, shared by all other abstracting interfaces, including static class wrappers (e.g. IPath) and factories (e.g. IDirectoryInfoFactory).

My suggestion would be to add an extra marker interface named like IFileSystemPathItem. The reason that I'm asking for this feature in the first place is because all 3 of the above file system entities exist in a file path in Windows. Analyzing a path, exploring directories, etc. are all improved via this abstraction without resorting to creating another wrapper on top of those.

@Rekkonnect : I am not sure I get, what you would gain by this. IFileInfo and IDirectoryInfo have a common interface, because they share a lot of functionality, but I don't see what functionality is shared with the IDriveInfo interface.
Could you please elaborate what you mean with "Analyzing a path, exploring directories" on a IDriveInfo?

So imagine I have the path: C:/users/user/desktop/file.txt. If I wanted to retrieve all parts of its path individually as IXyzInfo, I'd need:

• IDriveInfo for C:\ (I know IDirectoryInfo works but will instead need IDriveInfo for my use case)
• IDirectoryInfo for users/, user/, desktop/
• IFileInfo for file.txt

While there are no built-in APIs to get a IDriveInfo from IDirectoryInfo, I'm using my own logic to do that.

IDriveInfo indeed does not share much logic with IFileInfo and IDirectoryInfo. However, they're all capable of being present in a path. This common interface would bridge them all as viable parts of a path more than share much logic.

And I've found after all that this solution wouldn't quite end the problems there; I'd be then treating drives as non-directories when in reality all I need is all of IDirectoryInfo and IDriveInfo together.

I'm leaving this open for now, although don't find much real reason for it in the end. Maybe I'm missing something and misinterpreting the concepts.
