Can anyone recommend a usb flash drive I can use between my imac running o/s 10.4.11 and a pc running windows xp pro sp3 oem? I need to transfer .aif (aiff) files between my imac and the pc. The files will later be converted to .wav files. Can I just plug it in and copy the files or will I have to format the usb drive? So I can transfer the files to the pc? Thank you.
