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.

Our goal is to create a tool that:

• is completely free and open-source
• is updated and improved regularly, as much as personal circumstances of the developers permit
• supports a wide range of disk image containers, physical disk formats, file systems and partitioning schemes
• handles and reports exceptions properly
• offers other related advanced features that might come in handy

See the Status page for details about currently implemented features.

Here is a list of things we plan to support:

• 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

Please note that this list is not exhaustive nor definitive. We're open to adding support for more stuff in the future, but we have to start with the basics.

• Windows 7 Service Pack 1 or later
• .NET 5.0 runtime

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