As others have mentioned, a few options out there, however typically not quickly and easily performed. I've been migrating to Qemu, especially for simpler or older operating systems, rather than using Virtual Box. Best and easiest method for Qemu Check for partition sector size and start sector: $ fdisk -l start sector * sector size = mount offset Typically 63 start sector * 512 sector size = 32256 # mount -o loop,offset=32256 freedos.img /mnt/tmp Just remember, do not mount the image while an emulation or operating system is using the file system. Best practice, quickly mount, copy data, unmount. VirtualBox has vboximg-mount for mac osx, while Linux would need to use a raw image file format: $ VBoxManage clonehd --format RAW /path/to/your.vdi /path/to/your.img # mount -t ext3 -o loop,rw /path/to/your.img /path/to/mountpoint Otherwise, VirtualBox typically requires guest utilities installed into the guest operating system for sharing files to and fro while the virtualized operating system is running. Can be a real hassle after upgrades, due to guest utilities requiring upgrading too. Roger
