I can't say this is a bug or anything, but something seems kind of weird. In Windows 10, all files for which MC has a file association display "Media Center file" in the Type column of Windows Explorer. This isn't exactly wrong, I know. The problem is that if a folder has multiple file types, say some mp3 files and some jpg files, it is not possible to sort them by "Type" in file explorer. Yes, I can add a column to explorer for file extension, but it is only temporary. What's kind of weird is that it isn't normally the case for the Type column to display the name of the associated application. For example, if I use Windows settings to change the default app for mp3 files to Groove Music, then the Type for those files in explorer changes to "MP3 File." If I use windows to set the default app back to JRiver, the Type goes back to "Media Center file". Similarly for jpg files, if I set the default app to Photos. I have tried associating various file types to different applications and MC is the only one I have found where the type is always one value for all extensions. For this reason I think MC must be setting the value that is used by explorer for the Type column, and I'm wondering if this could possibly be changed so different file types in the same folder can be easily grouped.
