.aac files

Hello.....I just recorded an audio presentation and saved it.....the format is .aac . A colleague was practicing his presentation, and I wanted him to hear it.....

I'd like to give a copy to the presenter, so I copied it to a usb chip.......the trouble is, neither my Mac or my Windows machine recognizes the file.......can it be converted to a format that is transferrable?

Thanks!!!
