VirtualBox only works with floppy disk images which have a certain filename extension

Description (last modified by aeichner) (diff)

VirtualBox 4.0.4 seems to refuse to work with floppy disk images unless the image filename has a certain extension. For example, on selecting "myfloppy.bin" in the GUI, VirtualBox says:

Failed to open the floppy image /home/user/myfloppy.bin. Could not get the storage format of the medium '/home/user/myfloppy.bin' (VERR_NOT_SUPPORTED).

Result Code: VBOX_E_IPRT_ERROR (0x80BB0005) Component: Medium Interface: IMedium {9edda847-1279-4b0a-9af7-9d66251ccc18} Callee: IVirtualBox {d2de270c-1d4b-4c9e-843f-bbb9b47269ff}

However, if I rename the file to myfloppy.dsk, there is no problem. I suggest that the filename limitation be removed. (If the selected file is exactly 1474560 bytes long, it will be a raw floppy disk image.)

Supported extensions are .dsk, .img, .vfd, .ima. The extensions are used to differentiate between floppy and iso images. And a floppy can have different sizes (1.44 and 2.88MB for example). Closing as won't fix.
