Cannot access AMR files on windows?
When windows gives you an error message saying that it
"Cannot open AMR files", this means either:
A. You need to identify a program that can open the file
B. Or your registry may be damaged
Note: I'd add C. You may not have the proper codec installed that is associated with playing this type of file.
You may have to find and install the codec. Search the audio software manufacturer's website for the proper codec. If the codec is supposed to install with the program, try reinstalling or upgrading the software.
