# Windows 10 File Explorer says all IMG files are corrupt, but they are not

file-corruptionmountwindows 10windows-explorer

I have a large library of different IMG files (mostly from archived floppy disks). Whenever I open one with Windows Explorer, I get an error message that reads Could not mount file. The image file is corrupt.

I can confirm that the IMG files are not corrupted. They open just fine in a Windows XP virtual machine (which also means I can extract them to my host via a shared folder).

The virtual floppy disks I was trying to open were MS-DOS 6.22 Supplementary Disk and the Windows 95 (and ME) Boot Disks.

Why don't the files work in Windows 10?
