I also absolutely need explicit definitions for each field usage. It'd be really nice to know what actual name has been assigned to each data field in the Header structure just so I don't have to refer to 'the field located at offset X in the VDI Header.' The tutorial is great, but I need a lot more information. I had pulled TerryE's tutorial some time back, but I'm only just getting the chance to start looking over it.

BINARY HEADER FOR IPICTURE FORMAT PC
Using a similar method, I can expand fixed-sized VHD files at will by simply dropping a new empty file of the desired size onto my hard drive and then passing through the existing file bit-by-bit to make a mirror-image, then rewrite the header and footer to the appropriate value data so Virtual PC and VirtualBox can use them as if they were native, at which point I just have to start up the virtual machine and expand the primary partition (or create a new partition in the extra space).
BINARY HEADER FOR IPICTURE FORMAT MANUALS
I've been through the available open source repository, lots of Google search results, FAQs and manuals and I've found not one bit of data related to the actual binary image format of the VDI.Īs an example: I can download the binary-image spec for Microsoft's VHD file format, which enables me to create a small program to open and edit VHD Header and Footer data so I can (for example) straight copy a 25GB VHD file into a new folder, slap a fresh UUID on the copy VHD file in about a nanosecond, and then have the original and the copy loaded into VirtualBox simultaneously.
