Digital files are stored in digital filing cabinets called "directories" which are prone to "digital dust" - slight bit alterations that happen now or then. Now, admittedly, in its ideal, pristine condition, a piece of musical work encoded in FLAC format contains more information than the same piece encoded in MP3, however, as the FLAC file is bigger, it accumulates, in fact, MORE digital dust than the MP3 file. Now you might say that the density of dust is the same. That would be a naive view. Since MP3 files are smaller, they can be much more easily stacked together and held in "drawers" called archive files (Zip, Rar, Lha, etc.) ; in such a configuration, their surface-to-volume ratio is minimized. Thus, they accumulate LESS digital dust and thus decay at a much slower rate than FLACs. All this is well-known in academia, alas the ignorant hordes just think that because it's bigger, it must be better
A common mistake in academia. While this has been held as true for years, I recently got my hands on a cutting-edge report from the Digital Music Department at the University of Melbourne. They've shown that this files are actually cubes; the bits are stored in three dimensions. Since digital dust only accrues on the outside, FLAC files will have more dust, since they are thicker; but the internal bits are kept safe from decay, and the ratio of decay-to-bits is much lower even if the numbers of decay are higher. Mp3 stacking methods are effective, yes, but the files then cannot be easily retrieved.
