When I made large wav file with WavePad and save it, cannot open anymore if the file size is larger than about 6.3GB. Got "Error opening the file - Insufficient hard drive space to store the audio" message but the work space was on 1.5TB free HDD (2TB External HDD, USB3.0). Is this insufficient ? MacbookPro11,1 Intel Core i5 2.4GHz Memory 4GB, Yosemite 10.10.4 Free WavePad app 96KHz/24bit wav file Is this product specification ? or a bug ? or it needs disc space more ? Just curious.
