## Disk File Formats

Fuse supports several disk image formats in its +D and Beta 128 emulation.
The following are supported for reading:

.UDI

Ultra Disk Image; for specification details please see http://zxmak.narod.ru/docs.htm. This is the only image format which can store all the relevant information of the recorded data on a magnetic disk, so it can be used for any non standard disk format. Fuse can store and read both MFM and FM formatted disk data in/from this container.

.FDI

UKV Spectrum Debugger disk image format.

.MGT
.IMG

DISCiPLE/+D file formats.

.SAD
.SDF

For compatibility with SAM Coupé disk images using these formats. Note that SAM Coupé `.DSK' images share the same format as `.MGT'.

.TRD

TR-DOS disk image; for detailed information please see
http://www.retroplay.com/Mecenate/ramsoft/tr-info.zip

.SCL

A simple archive format for TR-DOS disk files.

.TD0

Teledisk image format; Fuse supports only files not created with "Advanced Compression". Detailed description found in http://www.classiccmp.org/dunfield/img/td0notes.txt and http://www.fpns.net/willy/wteledsk.htm.

.DSK

CPC disk image format; Fuse supports the plain old and the new extended CPC format too. Further information please see the The .DSK Format section and the CPCEMU manual section 7.7.1 http://www.cpc-emu.org/linux/cpcemu_e.txt.

.OPD
.OPU

Opus Discovery file formats.

Fuse supports the .UDI, .FDI, .MGT, .IMG, .SAD, .TRD, .SCL, .OPD, .OPU and .DSK (only the old CPC format) formats for writing.

You can save disk images with any output format, just select the appropriate type from the disk save dialog.

Not all image formats can store all disk image information. You cannot save a disk image with an inappropriate format that loses some information (e.g. variable track length or sector length).
