TotalImage is a free and open source disk image editor licensed under the MIT license. For more information, see the LICENSE file. It is written in C# and uses Windows Forms for the UI.

See the Status page for details about currently implemented features.

Currently the project is still in early stages of development (alpha-level), and as such is not quite ready for everyday use yet. We will provide official builds once we reach that stage, in the mean time you can build it yourself or ask us to provide binaries for you (see the Development and Support sections below).

• .NET 8.0 Desktop Runtime
• Windows 7 SP1/8.1/10/11

Support for other operating systems will be considered within the limitations of .NET.

Below is a list of things we plan to support. Please note that this list is not exhaustive nor definitive, and may change over time. We're open to adding support for more stuff in the future, but we have to start with the basics.

• Floppy disks
• Hard disks
• Optical discs
• Superfloppies

• Raw sector images (.IMG, .IMA etc.)
• TeleDisk (.TD0)
• ImageDisk (.IMD)
• 86Box 86F (.86F)
• Virtual Hard Disk (.VHD)
• ISO (.ISO)
• And more

• Common PC-compatible formats (160/180/320/360/720/1200/1440/1680/2880k)
• 8" formats (such as 1232k) and others with sector sizes larger/smaller than 512 bytes
• IBM XDF, DEC RX50 400k, Acorn 640k/800k, and more

• FAT12, FAT16, FAT32
• HPFS, NTFS
• High Sierra, ISO9660, UDF
• And more

• Various MBR variants
• GPT

To develop TotalImage, we recommend you install Microsoft Visual Studio 2022. This will give you the designer for Windows Forms, which makes it easier to work with the frontend.

Alternatively, you can also just build the solution with .NET CLI, which is included in the .NET SDK.
