To convert other file formats to the "Media Descriptor Sidecar" file type, you need software like Alcohol 120% or a similar tool.
About MDS files
The .MDS (Media Descriptor) file is primarily a metadata sidecar file used to structure data stored in a corresponding MDF (Media Disc Image File). Originally created for Alcohol 120% and Daemon Tools, this format is essential for reading copy-protected optical discs because it contains the track layout and sub-channel data that standard formats often discard.
While .MDS files are critical for accurate disc emulation, they present significant friction for modern users. First, an .MDS file is useless without its partner MDF file; users frequently download the small descriptor file (often just a few kilobytes) only to find the actual gigabytes of data are missing. Second, the format is proprietary and less compatible with standard operating system tools than the universal ISO format. For archiving and broad compatibility, the best solution is to convert the .MDS + MDF pair into a standard ISO file. If you are dealing with the less common HiTi ID Card design file (3% of users), these are proprietary vector layouts locked to specific printer software. Converting these to PDF or JPG allows for easy proofing and sharing without requiring the obscure HiTi ID Card Designer software.
Convert.Guru analyzes your MDS file, detects the exact format, and lets you read the text inside.
If you want to convert MDS file to ISO, CUE, PDF, BIN, MP3, MP4, CHD, IMG, DMG, VHD, VMDK or VDI, you can use Alcohol 120% or similar software from the "Disc Image Metadata" category. In the File menu, look for Save As… or Export….
To convert VFD, DMG, OVA, IMA, VBOX, ADF, PVS, VHD, OVF, ISO, DSK or IMG files to MDS, try Alcohol 120% or another comparable tool in the "Disc Image Metadata" category.
The MDS Converter Story
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 MDS converter.
