Errors in your registry are one of the common causes for incorrect file associations on your windows system. It is highly recommended that you check your registry for file association errors (will also check for any other registry errors).
The CHD file type is primarily associated with 'MAME' by MAME Team.
MAME = Multiple Arcade Machine Emulator.
MAME allows people to enjoy long-lost arcade games and even some newer ones; the main purpose of the project is to document the hardware (and software) of the arcade games.
Cannot access CHD files on windows?
When windows gives you an error message saying that it "Cannot open CHD files", this means either:
A. You need to identify a program that can open the file B. Or your registry may be damaged
RECOMMENDED:
In both cases it is strongly recommended that you run a free scan for registry errors.
