PC-size floppy disk image loads as trackdisk format

Is WinUAE supposed to support/work with PC floppy disk images? They are 737,280 or 1,474,560 bytes long for normal PC DD & HD formats. From winuaechangelog.txt it looks like they were supported since WinUAE 1.3.

Macintosh HD disks use the same 1.44MB format as PC/MS-DOS. I was wanting to select a Mac HD floppy image in DF0: for use with the A-Max Mac emulator.

When I do that, the disk icon appears on Workbench as DF0:LK` (LK being the first two bytes in the Mac disk image). WinUAE seems to be treating the disk as a normal Amiga/trackdisk HD floppy even though the image file is too small. I can use TrackDOS to read data from trackdisk.device, up to the ~1.44MB point. The same happens back to at least WinUAE 2.3.3 (the earliest version I tested). Or am I doing something wrong?

Edit: It looks like I have to rename the image file to end in .img for WinUAE to treat it as PC format?

It needs to have "known" extension (adf/adz/st/img/ima) and size must match with any common existing PC image format (number of sectors, tracks, dd or hh).

If no match, always mounted as normal adf. (Backwards compatibility, there are adfs floating around that are truncated and must still work)
