Disk Image Manager (previously SPIN Disk Manager) is a Windows application for examining and manipulating disk images in the Extended DSK format used by many Spectrum and Amstrad emulators.
The application was intended to complement the SPIN Spectrum emulator but is a complete standalone application. Many of this tools features and functions were driven by the Spectrum Disk Preservation team which use this format and tool to help manage the selection and testing of disk images archived to The World of Spectrum and The TZX Vault.
These images are traditionally created with CPDRead under DOS but I prefer to use Simon Owen’s fantastic SamDisk tool which works under Windows XP just great.
