There are 2 file types use the .MD0 file extension:
1. Alcohol Disk Image Segment 1
Contains an exact copy of a disc (such as a CD or DVD), copied by Alcohol 120% software; may be part of a sequence of disc image segments (such as MD0, .MD1, .MD2, etc.) or may be the only file.
MD0 files are often saved with a .MDF file or a .MDS file, which defines the tracks and data structure used by the disc.

2. Adobe Photoshop Metadata Cache File
File browsing cache file created by older versions of Adobe Photoshop, a an image-editing application; contains rotation and rank information for files browsed with the File Browser tool; used for caching metadata so that the program does not have to regenerate the information each time a user browses through image files.
MD0 files are saved with .TB0 files, which contain thumbnail image previews for the image files being browsed.
NOTE: The Adobe Photoshop File Browser tool has been recreated into the Adobe Bridge application, which is used for viewing and managing image files created in Adobe CS applications. Adobe Bridge CS5 stores cache information in files with the extensions .BC and .BCT.
