You cannot convert a .ZIP file to a .AUC file. A .ZIP file is an archive, and .AUC is audio. However, if there is an .AUC file located inside the .ZIP file, then you can extract it using software or even Windows internal .ZIP handling. First try double-clicking the .ZIP file to see if it opens. If it does, then deal with the files the same as you would files in a regular Windows folder. If not, then download PKZip, 7Zip, Rar!, or other archiver that handles .ZIP files. After installing an archiver, the likely action is to right-click the file you want to unzip and select unzip.
