This code is a batch script written for execution in a Windows command prompt or .bat file. Here is a step-by-step breakdown of what it does:

1. Iterates through all .chd files:
   for %%i in (*.chd) loops through all files with the .chd extension in the current directory.

2. Processes each .chd file in the loop: For each .chd file, the following operations are performed:

   • Extracts the .CHD file content:
     The command chdman extractcd -i "%%i" -o "%%~ni.cue" -ob "%%~ni.iso" calls chdman to extract the .chd file into two associated files:

     • %%~ni.cue: A CUE file derived from the name of the .chd file (without its extension);
     • %%~ni.iso: An ISO file also derived from the name of the .chd file.

     %%~ni is a batch variable that resolves to the base filename of %%i (the current .chd file), stripping the file extension.

   • Deletes the generated .CUE file:
     The command del "%%~ni.cue" deletes the extracted .cue file, leaving only the .iso file in the directory.

Summary:

The script converts every .chd file in the current directory into an .iso file (via the chdman tool) and immediately deletes the temporary .cue file created during that process. As a result, you'll be left with only .iso files corresponding to the original .chd files.
