Extract text from D64 files
To convert your D64 file to another format, you need VICE or other Disk Image software.
To convert other file formats to the "Commodore 1541 Floppy Image" file type, you need software like VICE or a similar tool.
A .d64 file is the standard disk image format for the Commodore 64, representing a sector-by-sector dump of a single-sided 1541 floppy disk. It typically weighs in at exactly 174,848 bytes. While it is the industry standard for emulation, it has a significant technical limitation: it stores only the "logical" sector data, discarding the raw Group Code Recording (GCR) magnetic information. This is why many copy-protected games fail to load in .d64 format; the protection checks look for intentional disk errors or "half-tracks" that the cleaned-up .d64 format cannot represent.
For general gameplay in emulators like VICE or CCS64, .d64 is sufficient. However, for digital preservation of original disks with copy protection, you should convert to or use the G64 format, which preserves the raw bit density. Users frequently need to "explode" a .d64 disk image to extract specific games as PRG (Program) files, or convert lists of BASIC code into readable TXT files. Managing these files often requires specialized tools like DirMaster or command-line utilities like cc1541, as modern operating systems cannot mount the CBM DOS file system natively.
Convert.Guru analyzes your D64 file, detects the exact format, and lets you read the text inside.
Users also converted T64, PRG, ZIP, CRT, TAP, G64, CBM and D81 files.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our D64 converter.
